From b02441999efcc6152b87cd58e7970bb7843f76cf Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Mon, 4 Nov 2013 23:13:25 +0800 Subject: Btrfs: don't wait for the completion of all the ordered extents It is very likely that there are lots of ordered extents in the filesytem, if we wait for the completion of all of them when we want to reclaim some space for the metadata space reservation, we would be blocked for a long time. The performance would drop down suddenly for a long time.
