Merge tag 'xfs-6.10-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux

Pull xfs fixes from Chandan Babu:

 - Fix a livelock by dropping an xfarray sortinfo folio when an error
   is encountered

 - During extended attribute operations, Initialize transaction
   reservation computation based on attribute operation code

 - Relax symbolic link's ondisk verification code to allow symbolic
   links with short remote targets

 - Prevent soft lockups when unmapping file ranges and also during
   remapping blocks during a reflink operation

 - Fix compilation warnings when XFS is built with W=1 option

* tag 'xfs-6.10-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
  xfs: Add cond_resched to block unmap range and reflink remap path
  xfs: don't open-code u64_to_user_ptr
  xfs: allow symlinks with short remote targets
  xfs: fix xfs_init_attr_trans not handling explicit operation codes
  xfs: drop xfarray sortinfo folio on error
  xfs: Stop using __maybe_unused in xfs_alloc.c
  xfs: Clear W=1 warning in xfs_iwalk_run_callbacks()
