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.
Closes-Bug: #1267983
Change-Id: Idd6158bfbe4dc049c33fa58b40d3d570fc244d01
