Subject: [f2fs-dev] [PATCH AUTOSEL 4.14 078/109] f2fs: fix to recover inode's project id during POR
Date: Sat,  9 Nov 2019 21:45:10 -0500
Message-ID: <20191110024541.31567-78-sashal@kernel.org> (raw)
In-Reply-To: <20191110024541.31567-1-sashal@kernel.org>

From: Chao Yu <yuchao0@huawei.com>

[ 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.
