From 06999f610afc3a123f7a54895e39d690301a8eba Mon Sep 17 00:00:00 2001 From: Eric Harney Date: Fri, 10 Jan 2014 14:20:41 -0500 Subject: [PATCH] GlusterFS: Synchronize additional operations create_cloned_volume() and copy_volume_to_image() should also be locked against other driver operations to prevent collisions from concurrent updates of snapshot metadata or volume file data.
