Subject: [PATCH 1/3] f2fs: fix to wait page writeback during revoking atomic write
Date: Mon, 23 Apr 2018 10:36:13 +0800 [thread overview]
Message-ID: <20180423023615.33247-1-yuchao0@huawei.com> (raw)
After revoking atomic write, related LBA can be reused by others, so we
need to wait page writeback before reusing the LBA, in order to avoid
interference between old atomic written in-flight IO and new IO.
