Linus Torvalds 0ee7c3e25d New code for 5.15:
- Simplify the bio_end_page usage in the buffered IO code.
  - Support reading inline data at nonzero offsets for erofs.
  - Fix some typos and bad grammar.
  - Convert kmap_atomic usage in the inline data read path.
  - Add some extra inline data input checking.
  - Fix a memory corruption bug stemming from iomap_swapfile_activate
    trying to activate more pages than mm was expecting.
  - Pass errnos through the page writeback code so that writeback errors
    are reported correctly instead of being munged to EIO.
  - Replace iomap_apply with a open-coded iterator loops to reduce the
    number of indirect calls by a third to a half.
  - Refactor the fsdax code to use iomap iterators instead of the
    open-coded iomap_apply code that it had before.
  - Format file range iomap tracepoint data in hexadecimal and
    standardize the names used in the pretty-print string.

Merge tag 'iomap-5.15-merge-4' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull iomap updates from Darrick Wong:
 "The most notable externally visible change for this cycle is the
  addition of support for reads to inline tail fragments of files, which
  was requested by the erofs developers; and a correction for a kernel
  memory corruption bug if the sysadmin tries to activate a swapfile
  with more pages than the swapfile header suggests.

  We also now report writeback completion errors to the file mapping
  correctly, instead of munging all errors into EIO.

  Internally, the bulk of the changes are Christoph's patchset to reduce
  the indirect function call count by a third to a half by converting
  iomap iteration from a loop pattern to a generator/consumer pattern.
  As an added bonus, fsdax no longer open-codes iomap apply loops.

  Summary:

   - Simplify the bio_end_page usage in the buffered IO code.

   - Support reading inline data at nonzero offsets for erofs.

   - Fix some typos and bad grammar.

   - Convert kmap_atomic usage in the inline data read path.

   - Add some extra inline data input checking.

   - Fix a memory corruption bug stemming from iomap_swapfile_activate
     trying to activate more pages than mm was expecting.

   - Pass errnos through the page writeback code so that writeback
     errors are reported correctly instead of being munged to EIO.

   - Replace iomap_apply with a open-coded iterator loops to reduce the
     number of indirect calls by a third to a half.

   - Refactor the fsdax code to use iomap iterators instead of the
     open-coded iomap_apply code that it had before.

   - Format file range iomap tracepoint data in hexadecimal and
     standardize the names used in the pretty-print string"
