H A Dtransaction.hdiff 60376ce4a8396bc5cd777be05b6a9bf044520f42 Fri Sep 14 09:34:40 CDT 2012 Josef Bacik <jbacik@fusionio.com> 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,
