Subject: [PATCH 3/8] writeback: use WRITE_BG for kupdate and background writeback
Date: Tue, 26 Apr 2016 09:55:26 -0600	[thread overview]
Message-ID: <1461686131-22999-4-git-send-email-axboe@fb.com> (raw)
In-Reply-To: <1461686131-22999-1-git-send-email-axboe@fb.com>

If we're doing background type writes, then use the appropriate
write command for that.

No functional changes in this patch.
