But you're right that now I don't see how that could be happening and it would be nice if we could get rid of this hack" [1] https://lore.kernel.org/linux-ext4/99cce8ca-e4a0-7301-840f-2ace67c551f3@huawei.com/T/#m04990cfbc4f44592421736b504afcc346b2a7c00 Related fix in ext4 by commit 72ffb49a7b62 ("ext4: do not set SB_ACTIVE in ext4_orphan_cleanup()"). f2fs has the same hack implementation in - f2fs_recover_orphan_inodes() - f2fs_recover_fsync_data() Let's get rid of this hack as well in f2fs.
