f2fs: fix to recover inode's project id during POR
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.
