Merge tag 'iomap-6.5-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull iomap fix from Darrick Wong:
"Fix partial write regression.
It turns out that fstests doesn't have any test coverage for short
writes, but LTP does. Fortunately, this was caught right after -rc1
was tagged.
Summary:
- Fix a bug wherein a failed write could clobber short write status"
* tag 'iomap-6.5-fixes-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
iomap: micro optimize the ki_pos assignment in iomap_file_buffered_write
