[ Upstream commit 19c73a691ccf6fb2f12d4e9cf9830023966cec88 ]
Testcase to reproduce this bug: 1. mkfs.f2fs /dev/sdd 2. mount -t f2fs /dev/sdd /mnt/f2fs 3. touch /mnt/f2fs/file 4. sync 5. chattr +A /mnt/f2fs/file 6. xfs_io -f /mnt/f2fs/file -c "fsync" 7. godown /mnt/f2fs 8. umount /mnt/f2fs 9. mount -t f2fs /dev/sdd /mnt/f2fs 10. lsattr /mnt/f2fs/file
-----------------N- /mnt/f2fs/file
But actually, we expect the corrct result is:
-------A---------N- /mnt/f2fs/file
The reason is we didn't recover inode.i_flags field during mount, fix it.
