Subject: [PATCH 3/8] writeback: use WRITE_BG for kupdate and background writeback
Date: Wed, 31 Aug 2016 11:05:46 -0600 [thread overview]
Message-ID: <1472663151-18560-4-git-send-email-axboe@fb.com> (raw)
In-Reply-To: <1472663151-18560-1-git-send-email-axboe@fb.com>
If we're doing background type writes, then use the appropriate
write command for that.
