Latest commit dcdc4f1 Sep 2, 2016 @peter-wangxu peter-wangxu Switch to conditional lock
This patch enables conditional lock for initialize_connection and

* When destroy_empty_storage_group = False, no lock for above interfaces
* When destroy_empty_storage_group = True, lock for both just behave
  like previous driver

Previously, vnx driver has a lock for a certain storage group,
now, with this patch, driver can performe multiple attachments/detachments
for a certain host(storage group) concurrently when
