Date: Mon, 24 Aug 2015 11:09:38 +0200 From: Jiri Slaby <jslaby@...e.cz> To: stable@...r.kernel.org Cc: linux-kernel@...r.kernel.org, Joe Thornber <ejt@...hat.com>, Mike Snitzer <snitzer@...hat.com>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 3.12 78/82] dm thin metadata: delete btrees when releasing metadata snapshot From: Joe Thornber <ejt@...hat.com> 3.12-stable review patch. If anyone has any objections, please let me know. =============== commit 7f518ad0a212e2a6fd68630e176af1de395070a7 upstream. The device details and mapping trees were just being decremented before. Now btree_del() is called to do a deep delete.
