From 60376ce4a8396bc5cd777be05b6a9bf044520f42 Mon Sep 17 00:00:00 2001 From: Josef Bacik Date: Fri, 14 Sep 2012 10:34:40 -0400 Subject: [PATCH] Btrfs: fix race in sync and freeze again I screwed this up, there is a race between checking if there is a running transaction and actually starting a transaction in sync where we could race with a freezer and get ourselves into trouble. To fix this we need to make a new join type to only do the try lock on the freeze stuff. If it fails we'll return EPERM and just return from sync. This fixes a hang Liu Bo reported when running xfstest 68 in a loop. Thanks, Reported-by: Liu Bo Signed-off-by: Josef Bacik --- Reading git-format-patch failed
