This series is provoked by syzbot warnings caused by corrupted directory inode with i_nlink == 1 that passes the initial sanity check which will only mark the filesystem as corrupted in case i_nlink == 0.
Tests: - fio/fsmark parallel create/unlink on VM with f2fs root filesystem. - syzbot Changelog: Changes from v1: - Rename exit label in f2fs_unlink(). - Add sanity check in sanity_check_inode() and remove it from f2fs_iget(). as suggested by Chao Yu in order to detect on-disk corruption early. https://lore.kernel.org/linux-f2fs-devel/[email protected]/T/#t Nikola Z.
