3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Joe Thornber <ejt@redhat.com> commit 7f518ad0a212e2a6fd68630e176af1de395070a7 upstream. The device details and mapping trees were just being decremented before. Now btree_del() is called to do a deep delete.
