f2fs: report error if quota off error during umount
Now, we depend on fsck to ensure quota file data is ok, so we scan whole partition if checkpoint without umount flag. It's same for quota off error case, which may make quota file data inconsistent. generic/019 reports below error: __quota_error: 1160 callbacks suppressed Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota Quota error (device zram1): write_blk: dquota write failed Quota error (device zram1): qtree_write_dquot: Error -28 occurred while creating quota VFS: Busy inodes after unmount of zram1. Self-destruct in 5 seconds. Have a nice day... If we failed in below path due to fail to write dquot block, we will miss to release quota inode, fix it. - f2fs_put_super - f2fs_quota_off_umount - f2fs_quota_off - f2fs_quota_sync <-- failed - dquot_quota_off <-- missed to call Signed-off-by: Yunlei He <heyunlei@huawei.com> Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
