0974f486f3 f2fs-for-6.17-rc1
In this round, we've mainly updated three parts: 1) folio conversion by Matthew,
 2) switch to a new mount API by Hongbo and Eric, and 3) several sysfs entries
 to tune GCs for ZUFS with finer granularity by Daeho. There are also patches
 to address bugs and issues in the existing features such as GCs, file pinning,
 write-while-dio-read, contingous block allocation, and memory access violations.
 
 Enhancement:
  - switch to new mount API and folio conversion
  - add sysfs nodes to controle F2FS GCs for ZUFS
  - improve performance on the nat entry cache
  - drop inode from the donation list when the last file is closed
  - avoid splitting bio when reading multiple pages
 
 Bug fix:
  - fix to trigger foreground gc during f2fs_map_blocks() in lfs mode
  - make sure zoned device GC to use FG_GC in shortage of free section
  - fix to calculate dirty data during has_not_enough_free_secs()
  - fix to update upper_p in __get_secs_required() correctly
  - wait for inflight dio completion, excluding pinned files read using dio
  - don't break allocation when crossing contiguous sections
  - vm_unmap_ram() may be called from an invalid context
  - fix to avoid out-of-boundary access in dnode page
  - fix to avoid panic in f2fs_evict_inode
  - fix to avoid UAF in f2fs_sync_inode_meta()
  - fix to use f2fs_is_valid_blkaddr_raw() in do_write_page()
  - fix UAF of f2fs_inode_info in f2fs_free_dic
  - fix to avoid invalid wait context issue
  - fix bio memleak when committing super block
  - handle nat.blkaddr corruption in f2fs_get_node_info()
 
 In addition, there are also clean-ups and minor bug fixes.

Pull apparmor updates from John Johansen:
 "This has one major feature, it pulls in a cleaned up version of
  af_unix mediation that Ubuntu has been carrying for years. It is
  placed behind a new abi to ensure that it does cause policy
  regressions. With pulling in the af_unix mediation there have been
  cleanups and some refactoring of network socket mediation. This
  accounts for the majority of the changes in the diff.

  In addition there are a few improvements providing minor code
  optimizations. several code cleanups, and bug fixes.

  Features:
   - improve debug printing
   - carry mediation check on label (optimization)
   - improve ability for compiler to optimize
     __begin_current_label_crit_section
   - transition for a linked list of rulesets to a vector of rulesets
   - don't hardcode profile signal, allow it to be set by policy

5f49c2d1f4 apparmor: fix: oops when trying to free null ruleset
profile allocation is wrongly setting the number of entries on the
rules vector before any ruleset is assigned. If profile allocation
fails between ruleset allocation and assigning the first ruleset,
free_ruleset() will be called with a null pointer resulting in an
oops.

- The 2 patch series "squashfs: Remove page->mapping references" from
   Matthew Wilcox gets us closer to being able to remove page->mapping.
 
 - The 5 patch series "relayfs: misc changes" from Jason Xing does some
   maintenance and minor feature addition work in relayfs.
 
 - The 5 patch series "kdump: crashkernel reservation from CMA" from Jiri
   Bohac switches us from static preallocation of the kdump crashkernel's
   working memory over to dynamic allocation.  So the difficulty of
   a-priori estimation of the second kernel's needs is removed and the
   first kernel obtains extra memory.
 
 - The 5 patch series "generalize panic_print's dump function to be used
   by other kernel parts" from Feng Tang implements some consolidation and
   rationalizatio of the various ways in which a faiing kernel splats
   information at the operator.

   - "squashfs: Remove page->mapping references" (Matthew Wilcox) gets
     us closer to being able to remove page->mapping

   - "relayfs: misc changes" (Jason Xing) does some maintenance and
     minor feature addition work in relayfs

   - "kdump: crashkernel reservation from CMA" (Jiri Bohac) switches
     us from static preallocation of the kdump crashkernel's working
     memory over to dynamic allocation. So the difficulty of a-priori
     estimation of the second kernel's needs is removed and the first
     kernel obtains extra memory

   - "generalize panic_print's dump function to be used by other
     kernel parts" (Feng Tang) implements some consolidation and
     rationalization of the various ways in which a failing kernel

3c4a063b1f tracing cleanups for v6.17:
- Remove unneeded goto out statements
 
   Over time, the logic was restructured but left a "goto out" where the
   out label simply did a "return ret;". Instead of jumping to this out
   label, simply return immediately and remove the out label.
 
 - Add guard(ring_buffer_nest)
 
   Some calls to the tracing ring buffer can happen when the ring buffer is
   already being written to at the same context (for example, a
   trace_printk() in between a ring_buffer_lock_reserve() and a
   ring_buffer_unlock_commit()).
 
   In order to not trigger the recursion detection, these functions use
   ring_buffer_nest_start() and ring_buffer_nest_end(). Create a guard() for
   these functions so that their use cases can be simplified and not need to
   use goto for the release.
 
 - Clean up the tracing code with guard() and __free() logic
 
   There were several locations that were prime candidates for using guard()
   and __free() helpers. Switch them over to use them.
 
 - Fix output of function argument traces for unsigned int values
 
   The function tracer with "func-args" option set will record up to 6 argument
   registers and then use BTF to format them for human consumption when the
   trace file is read. There's several arguments that are "unsigned long" and
   even "unsigned int" that are either and address or a mask. It is easier to
   understand if they were printed using hexadecimal instead of decimal.
   The old method just printed all non-pointer values as signed integers,
   which made it even worse for unsigned integers.
 
   For instance, instead of:
 
     __local_bh_disable_ip(ip=-2127311112, cnt=256) <-handle_softirqs
 
   Show:
 
    __local_bh_disable_ip(ip=0xffffffff8133cef8, cnt=0x100) <-handle_softirqs

8877fcb70f This is a small set of changes for modules, primarily to extend module users
to use the module data structures in combination with the already no-op stub
 module functions, even when support for modules is disabled in the kernel
 configuration. This change follows the kernel's coding style for conditional
 compilation and allows kunit code to drop all CONFIG_MODULES ifdefs, which is
 also part of the changes. This should allow others part of the kernel to do the
 same cleanup.
 
 Note that this had a conflict with sysctl changes [1] but should be fixed now as I
 rebased on top.
 
 The remaining changes include a fix for module name length handling which could
 potentially lead to the removal of an incorrect module, and various cleanups.
 
 The module name fix and related cleanup has been in linux-next since Thursday
 (July 31) while the rest of the changes for a bit more than 3 weeks.
 
 Note that this currently has conflicts in next with kbuild's tree [2].

352af6a011 Rust changes for v6.17
Toolchain and infrastructure:
 
  - Enable a set of Clippy lints: 'ptr_as_ptr', 'ptr_cast_constness',
    'as_ptr_cast_mut', 'as_underscore', 'cast_lossless' and 'ref_as_ptr'.
 
    These are intended to avoid type casts with the 'as' operator, which
    are quite powerful, into restricted variants that are less powerful
    and thus should help to avoid mistakes.
 
  - Remove the 'author' key now that most instances were moved to the
    plural one in the previous cycle.
 
 'kernel' crate:
 
  - New 'bug' module: add 'warn_on!' macro which reuses the existing
    'BUG'/'WARN' infrastructure, i.e. it respects the usual sysctls and
    kernel parameters:
 
        warn_on!(value == 42);
 
    To avoid duplicating the assembly code, the same strategy is followed
    as for the static branch code in order to share the assembly between
    both C and Rust. This required a few rearrangements on C arch headers
    -- the existing C macros should still generate the same outputs, thus
    no functional change expected there.
 
  - 'workqueue' module: add delayed work items, including a 'DelayedWork'
    struct, a 'impl_has_delayed_work!' macro and an 'enqueue_delayed'
    method, e.g.:
 
        /// Enqueue the struct for execution on the system workqueue,
        /// where its value will be printed 42 jiffies later.
        fn print_later(value: Arc<MyStruct>) {
            let _ = workqueue::system().enqueue_delayed(value, 42);
        }
 
  - New 'bits' module: add support for 'bit' and 'genmask' functions,
    with runtime- and compile-time variants, e.g.:
 
        static_assert!(0b00010000 == bit_u8(4));
        static_assert!(0b00011110 == genmask_u8(1..=4));
 
        assert!(checked_bit_u32(u32::BITS).is_none());
 
  - 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which reads
    NUL-terminated strings from userspace into a '&CStr'.
 
    Introduce 'UserPtr' newtype, similar in purpose to '__user' in C, to
    minimize mistakes handling userspace pointers, including mixing them
    up with integers and leaking them via the 'Debug' trait. Add it to
    the prelude, too.
 
  - Start preparations for the replacement of our custom 'CStr' type
    with the analogous type in the 'core' standard library. This will
    take place across several cycles to make it easier. For this one,
    it includes a new 'fmt' module, using upstream method names and some
    other cleanups.
 
    Replace 'fmt!' with a re-export, which helps Clippy lint properly,
    and clean up the found 'uninlined-format-args' instances.
 
  - 'dma' module:
 
    - Clarify wording and be consistent in 'coherent' nomenclature.
 
    - Convert the 'read!()' and 'write!()' macros to return a 'Result'.
 
    - Add 'as_slice()', 'write()' methods in 'CoherentAllocation'.
 
    - Expose 'count()' and 'size()' in 'CoherentAllocation' and add the
      corresponding type invariants.
 
    - Implement 'CoherentAllocation::dma_handle_with_offset()'.
 
  - 'time' module:
 
    - Make 'Instant' generic over clock source. This allows the compiler
      to assert that arithmetic expressions involving the 'Instant' use
      'Instants' based on the same clock source.
 
    - Make 'HrTimer' generic over the timer mode. 'HrTimer' timers take a
      'Duration' or an 'Instant' when setting the expiry time, depending
      on the timer mode. With this change, the compiler can check the
      type matches the timer mode.
 
    - Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
      function that will select an appropriate sleep method depending on
      the requested sleep time.
 
    - Avoid 64-bit divisions on 32-bit hardware when calculating
      timestamps.
 
    - Seal the 'HrTimerMode' trait. This prevents users of the
      'HrTimerMode' from implementing the trait on their own types.
 
    - Pass the correct timer mode ID to 'hrtimer_start_range_ns()'.
 
  - 'list' module: remove 'OFFSET' constants, allowing to remove pointer
    arithmetic; now 'impl_list_item!' invokes 'impl_has_list_links!' or
    'impl_has_list_links_self_ptr!'. Other simplifications too.
 
  - 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
    constant, which avoids exposing the type of the opaque pointer, and
    require 'into_foreign' to return non-null.
 
    Remove the 'Either<L, R>' type as well. It is unused, and we want to
    encourage the use of custom enums for concrete use cases.
 
  - 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
    to allow them to be used in generic APIs.
 
  - 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
     and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'.
 
  - 'Opaque' type: add 'cast_from' method to perform a restricted cast
    that cannot change the inner type and use it in callers of
    'container_of!'. Rename 'raw_get' to 'cast_into' to match it.
 
  - 'rbtree' module: add 'is_empty' method.
 
  - 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
    'ARef', which are moved from the too general 'types' module which we
    want to reduce or eventually remove. Also fix a safety comment in
    'static_lock_class'.
 
 'pin-init' crate:
 
  - Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are now
    (pin-)initializers.
 
  - Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'.
 
  - New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
    it via 'Zeroable::zeroed()'.
 
  - Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
    'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for '"Rust"'
    and '"C"' ABIs and up to 20 arguments.
 
  - Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
    [Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'.
 
  - Renamed 'zeroed()' to 'init_zeroed()'.
 
  - Upstream dev news: improve CI more to deny warnings, use
    '--all-targets'. Check the synchronization status of the two '-next'
    branches in upstream and the kernel.
 
 MAINTAINERS:
 
  - Add Vlastimil Babka, Liam R. Howlett, Uladzislau Rezki and Lorenzo
    Stoakes as reviewers (thanks everyone).
 
 And a few other cleanups and improvements.

   - 'uaccess' module: add 'UserSliceReader::strcpy_into_buf', which
     reads NUL-terminated strings from userspace into a '&CStr'

     Introduce 'UserPtr' newtype, similar in purpose to '__user' in C,
     to minimize mistakes handling userspace pointers, including mixing
     them up with integers and leaking them via the 'Debug' trait. Add
     it to the prelude, too

   - Start preparations for the replacement of our custom 'CStr' type
     with the analogous type in the 'core' standard library. This will
     take place across several cycles to make it easier. For this one,
     it includes a new 'fmt' module, using upstream method names and
     some other cleanups

     Replace 'fmt!' with a re-export, which helps Clippy lint properly,
     and clean up the found 'uninlined-format-args' instances

   - 'dma' module:

      - Clarify wording and be consistent in 'coherent' nomenclature

      - Convert the 'read!()' and 'write!()' macros to return a 'Result'

      - Add 'as_slice()', 'write()' methods in 'CoherentAllocation'

      - Expose 'count()' and 'size()' in 'CoherentAllocation' and add
        the corresponding type invariants

      - Implement 'CoherentAllocation::dma_handle_with_offset()'

   - 'time' module:

      - Make 'Instant' generic over clock source. This allows the
        compiler to assert that arithmetic expressions involving the
        'Instant' use 'Instants' based on the same clock source

      - Make 'HrTimer' generic over the timer mode. 'HrTimer' timers
        take a 'Duration' or an 'Instant' when setting the expiry time,
        depending on the timer mode. With this change, the compiler can
        check the type matches the timer mode

      - Add an abstraction for 'fsleep'. 'fsleep' is a flexible sleep
        function that will select an appropriate sleep method depending
        on the requested sleep time

      - Avoid 64-bit divisions on 32-bit hardware when calculating
        timestamps

      - Seal the 'HrTimerMode' trait. This prevents users of the
        'HrTimerMode' from implementing the trait on their own types

      - Pass the correct timer mode ID to 'hrtimer_start_range_ns()'

   - 'list' module: remove 'OFFSET' constants, allowing to remove
     pointer arithmetic; now 'impl_list_item!' invokes
     'impl_has_list_links!' or 'impl_has_list_links_self_ptr!'. Other
     simplifications too

   - 'types' module: remove 'ForeignOwnable::PointedTo' in favor of a
     constant, which avoids exposing the type of the opaque pointer, and
     require 'into_foreign' to return non-null

     Remove the 'Either<L, R>' type as well. It is unused, and we want
     to encourage the use of custom enums for concrete use cases

   - 'sync' module: implement 'Borrow' and 'BorrowMut' for 'Arc' types
     to allow them to be used in generic APIs

   - 'alloc' module: implement 'Borrow' and 'BorrowMut' for 'Box<T, A>';
     and 'Borrow', 'BorrowMut' and 'Default' for 'Vec<T, A>'

   - 'Opaque' type: add 'cast_from' method to perform a restricted cast
     that cannot change the inner type and use it in callers of
     'container_of!'. Rename 'raw_get' to 'cast_into' to match it

   - 'rbtree' module: add 'is_empty' method

   - 'sync' module: new 'aref' submodule to hold 'AlwaysRefCounted' and
     'ARef', which are moved from the too general 'types' module which
     we want to reduce or eventually remove. Also fix a safety comment
     in 'static_lock_class'

  'pin-init' crate:

   - Add 'impl<T, E> [Pin]Init<T, E> for Result<T, E>', so results are
     now (pin-)initializers

   - Add 'Zeroable::init_zeroed()' that delegates to 'init_zeroed()'

   - New 'zeroed()', a safe version of 'mem::zeroed()' and also provide
     it via 'Zeroable::zeroed()'

   - Implement 'Zeroable' for 'Option<&T>', 'Option<&mut T>' and for
     'Option<[unsafe] [extern "abi"] fn(...args...) -> ret>' for
     '"Rust"' and '"C"' ABIs and up to 20 arguments

   - Changed blanket impls of 'Init' and 'PinInit' from 'impl<T, E>
     [Pin]Init<T, E> for T' to 'impl<T> [Pin]Init<T> for T'

   - Renamed 'zeroed()' to 'init_zeroed()'

   - Upstream dev news: improve CI more to deny warnings, use
     '--all-targets'. Check the synchronization status of the two
     '-next' branches in upstream and the kernel

  MAINTAINERS:

   - Add Vlastimil Babka, Liam R. Howlett, Uladzislau Rezki and Lorenzo
     Stoakes as reviewers (thanks everyone)

  And a few other cleanups and improvements"

0b7c9528fa i2c: Force DLL0945 touchpad i2c freq to 100khz
This patch fixes an issue where the touchpad cursor movement becomes
slow on the Dell Precision 5560. Force the touchpad freq to 100khz
as a workaround.

Tested on Dell Precision 5560 with 6.14 to 6.14.6. Cursor movement
is now smooth and responsive.

65cf62cd62 i2c: apple: Drop default ARCH_APPLE in Kconfig
When the first driver for Apple Silicon was upstreamed we accidentally
included `default ARCH_APPLE` in its Kconfig which then spread to almost
every subsequent driver. As soon as ARCH_APPLE is set to y this will
pull in many drivers as built-ins which is not what we want.
Thus, drop `default ARCH_APPLE` from Kconfig.

186f3edfdd Pin control changes for v6.17
Core changes:
 
 - Open code PINCTRL_FUNCTION_DESC() instead of defining
   a complex macro only used in one place.
 
 - Add pinmux_generic_add_pinfunction() helper and
   use this in a few drivers.
 
 New drivers:
 
 - Amlogic S7, S7D and S6 pin control support.
 
 - Eswin EIC7700 pin control support.
 
 - Qualcomm PMIV0104, PM7550 and Milos pin control
   support.
 
   Because of unhelpful numbering schemes, the Qualcomm
   driver now needs to start to rely on SoC codenames.
 
 - STM32 HDP pin control support.
 
 - Mediatek MT8189 pin control support.
 
 Improvements:
 
 - Switch remaining pin control drivers over to the
   new GPIO set callback that provides a return value.
 
 - Support RSVD (reserved) pins in the STM32 driver.
 
 - Move many fixed assignments over to pinctrl_desc
   definitions.
 
 - Handle multiple TLMM regions in the Qualcomm driver.

a2152fef29 mm: mempool: fix crash in mempool_free() for zero-minimum pools
The mempool wake-up fix introduced in commit a5867a218d ("mm: mempool:
fix wake-up edge case bug for zero-minimum pools") inlined the
add_element() logic in mempool_free() to return the element to the
zero-minimum pool:

pool->elements[pool->curr_nr++] = element;

This causes crash, because mempool_init_node() does not initialize with
real allocation for zero-minimum pool, it only returns ZERO_SIZE_PTR to
the elements array which is unable to be dereferenced, and the
pre-allocation of this array never happened since the while test:

while (pool->curr_nr < pool->min_nr)

can never be satisfied as min_nr is zero, so the pool does not actually
reserve any buffer, the only way so far is to call alloc_fn() to get
buffer from SLUB, but if the memory is under high pressure the alloc_fn()
could never get any buffer, the waiting thread would be in an indefinite
loop of wake-sleep in a period until there is free memory to get.

This patch changes mempool_init_node() to allocate 1 element for the
elements array of zero-minimum pool, so that the pool will have reserved
buffer to use.  This will fix the crash issue and let the waiting thread
can get the reserved element when alloc_fn() failed to get buffer under
high memory pressure.

Also modify add_element() to support zero-minimum pool with simplifying
codes of zero-minimum handling in mempool_free().

f04fd85f15 mm: correct type for vmalloc vm_flags fields
Several functions refer to the unfortunately named 'vm_flags' field when
referencing vmalloc flags, which happens to be the precise same name used
for VMA flags.

As a result these were erroneously changed to use the vm_flags_t type
(which currently is a typedef equivalent to unsigned long).

Currently this has no impact, but in future when vm_flags_t changes this
will result in issues, so change the type to unsigned long to account for
this.

de55be4237 mm/shmem, swap: fix major fault counting
If the swapin failed, don't update the major fault count.  There is a long
existing comment for doing it this way, now with previous cleanups, we can
finally fix it.

93c0476e70 mm/shmem, swap: rework swap entry and index calculation for large swapin
Instead of calculating the swap entry differently in different swapin
paths, calculate it early before the swap cache lookup and use that for
the lookup and later swapin.  And after swapin have brought a folio,
simply round it down against the size of the folio.

This is simple and effective enough to verify the swap value.  A folio's
swap entry is always aligned by its size.  Any kind of parallel split or
race is acceptable because the final shmem_add_to_page_cache ensures that
all entries covered by the folio are correct, and thus there will be no
data corruption.

This also prevents false positive cache lookup.  If a shmem read request's
index points to the middle of a large swap entry, previously, shmem will
try the swap cache lookup using the large swap entry's starting value
(which is the first sub swap entry of this large entry).  This will lead
to false positive lookup results if only the first few swap entries are
cached but the actual requested swap entry pointed by the index is
uncached.  This is not a rare event, as swap readahead always tries to
cache order 0 folios when possible.

And this shouldn't cause any increased repeated faults.  Instead, no
matter how the shmem mapping is split in parallel, as long as the mapping
still contains the right entries, the swapin will succeed.

The final object size and stack usage are also reduced due to simplified
code:

./scripts/bloat-o-meter mm/shmem.o.old mm/shmem.o
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-145 (-145)
Function                                     old     new   delta
shmem_swapin_folio                          4056    3911    -145
Total: Before=33242, After=33097, chg -0.44%

Stack usage (Before vs After):
mm/shmem.c:2314:12:shmem_swapin_folio   264     static
mm/shmem.c:2314:12:shmem_swapin_folio   256     static

And while at it, round down the index too if swap entry is round down. 
The index is used either for folio reallocation or confirming the mapping
content.  In either case, it should be aligned with the swap folio.

1326359f22 mm/shmem, swap: simplify swapin path and result handling
Slightly tidy up the different handling of swap in and error handling for
SWP_SYNCHRONOUS_IO and non-SWP_SYNCHRONOUS_IO devices.  Now swapin will
always use either shmem_swap_alloc_folio or shmem_swapin_cluster, then
check the result.

Simplify the control flow and avoid a redundant goto label.

69805ea79d mm/shmem, swap: never use swap cache and readahead for SWP_SYNCHRONOUS_IO
For SWP_SYNCHRONOUS_IO devices, if a cache bypassing THP swapin failed due
to reasons like memory pressure, partially conflicting swap cache or ZSWAP
enabled, shmem will fallback to cached order 0 swapin.

Right now the swap cache still has a non-trivial overhead, and readahead
is not helpful for SWP_SYNCHRONOUS_IO devices, so we should always skip
the readahead and swap cache even if the swapin falls back to order 0.

So handle the fallback logic without falling back to the cached read.

91ab656ece mm/shmem, swap: tidy up swap entry splitting
Instead of keeping different paths of splitting the entry before the swap
in start, move the entry splitting after the swapin has put the folio in
swap cache (or set the SWAP_HAS_CACHE bit).  This way we only need one
place and one unified way to split the large entry.  Whenever swapin
brought in a folio smaller than the shmem swap entry, split the entry and
recalculate the entry and index for verification.

This removes duplicated codes and function calls, reduces LOC, and the
split is less racy as it's guarded by swap cache now.  So it will have a
lower chance of repeated faults due to raced split.  The compiler is also
able to optimize the coder further:

bloat-o-meter results with GCC 14:

With DEBUG_SECTION_MISMATCH (-fno-inline-functions-called-once):
./scripts/bloat-o-meter mm/shmem.o.old mm/shmem.o
add/remove: 0/0 grow/shrink: 0/1 up/down: 0/-143 (-143)
Function                                     old     new   delta
shmem_swapin_folio                          2358    2215    -143
Total: Before=32933, After=32790, chg -0.43%

With !DEBUG_SECTION_MISMATCH:
add/remove: 0/1 grow/shrink: 1/0 up/down: 1069/-749 (320)
Function                                     old     new   delta
shmem_swapin_folio                          2871    3940   +1069
shmem_split_large_entry.isra                 749       -    -749
Total: Before=32806, After=33126, chg +0.98%

Since shmem_split_large_entry is only called in one place now. The
compiler will either generate more compact code, or inlined it for
better performance.
