Merge tag 'f2fs-fix-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs
Pull f2fs fixes from Jaegeuk Kim:
"This includes major bug fixes introduced in 5.18-rc1 and 5.17+:
- Remove obsolete whint_mode (5.18-rc1)
- Fix IO split issue caused by op_flags change in f2fs (5.18-rc1)
- Fix a wrong condition check to detect IO failure loop (5.18-rc1)
- Fix wrong data truncation during roll-forward (5.17+)"
* tag 'f2fs-fix-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs:
f2fs: should not truncate blocks during roll-forward recovery
f2fs: fix wrong condition check when failing metapage read
f2fs: keep io_flags to avoid IO split due to different op_flags in two fio holders
f2fs: remove obsolete whint_mode
