From a5991428064e98c7367fe1c1686ea6a23fb6a4b3 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 15 Jul 2011 16:01:03 +0000 Subject: Btrfs: don't flush delalloc arbitrarily Kill the check to see if we have 512mb of reserved space in delalloc and shrink_delalloc if we do. This causes unexpected latencies and we have other logic to see if we need to throttle.
