Date: Tue, 20 Apr 2010 12:41:54 +1000 From: Dave Chinner <david@...morbit.com> To: linux-fsdevel@...r.kernel.org Cc: linux-kernel@...r.kernel.org, xfs@....sgi.com Subject: [PATCH 4/4] xfs: remove nr_to_write writeback windup. From: Dave Chinner <dchinner@...hat.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.
