Subject: [PATCH 5/6] xfs: remove nr_to_write writeback windup.
Date: Tue, 25 May 2010 20:54:11 +1000 [thread overview]
Message-ID: <1274784852-30502-6-git-send-email-david@fromorbit.com> (raw)
In-Reply-To: <1274784852-30502-1-git-send-email-david@fromorbit.com>
From: Dave Chinner <dchinner@redhat.com>
Now that the background flush code has been fixed, we shouldn't need to
silently multiply the wbc->nr_to_write to get good writeback. Remove
that code.
