Subject: [PATCH 1/2] f2fs: report error if quota off error during umount
Date: Thu, 6 Sep 2018 20:44:35 +0800	[thread overview]
Message-ID: <20180906124436.89193-1-yuchao0@huawei.com> (raw)

From: Yunlei He <heyunlei@huawei.com>

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.
