xfs: move xfs_attr_use_log_assist out of xfs_log.c The LARP patchset added an awkward coupling point between libxfs and what would be libxlog, if the XFS log were actually its own library. Move the code that enables logged xattr updates out of "lib"xlog and into xfs_xattr.c so that it no longer has to know about xlog_* functions. While we're at it, give xfs_xattr.c its own header file.

xfs: remove xfs_da_args.attr_flags This field only ever contains XATTR_{CREATE,REPLACE}, and it only goes as deep as xfs_attr_set. Remove the field from the structure and replace it with an enum specifying exactly what kind of change we want to make to the xattr structure. Upsert is the name that we'll give to the flags==0 operation, because we're either updating an existing value or inserting it, and the caller doesn't care. Note: The "UPSERTR" name created here is to make userspace porting easier. It will be removed in the next patch. Signed-off-by: Darrick J.

xfs: move xfs_xattr_handlers to .rodata This makes it harder for accidental or malicious changes to xfs_xattr_handlers at runtime. Cc: "Darrick J.
