From 254c8c2dbf0e06a560a5814eb90cb628adb2de66 Mon Sep 17 00:00:00 2001 From: Dave Chinner Date: Wed, 9 Jun 2010 10:37:19 +1000 Subject: [PATCH] xfs: remove nr_to_write writeback windup. 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.
