[ Upstream commit f4474aa6e5e901ee4af21f39f1b9115aaaaec503 ]
Testcase to reproduce this bug: 1. mkfs.f2fs -O extra_attr -O project_quota /dev/sdd 2. mount -t f2fs /dev/sdd /mnt/f2fs 3. touch /mnt/f2fs/file 4. sync 5. chattr -p 1 /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 -p /mnt/f2fs/file
0 -----------------N- /mnt/f2fs/file
But actually, we expect the correct result is:
1 -----------------N- /mnt/f2fs/file
The reason is we didn't recover inode.i_projid field during mount, fix it.
