Subject: [PATCH 1/6] f2fs: fix to recover inode's project id during POR
Date: Tue, 25 Sep 2018 15:35:58 +0800 [thread overview]
Message-ID: <20180925073603.102125-1-yuchao0@huawei.com> (raw)
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.
