From b5b09be30cf99f9c699e825629f02e3bce555d44 Mon Sep 17 00:00:00 2001 From: Alex Elder Date: Wed, 1 May 2013 21:37:07 -0500 Subject: [PATCH] rbd: fix image request leak on parent read When a read for a layered image object finds the target object doesn't exist, a read image request for the parent image is created and submitted. When that completes, the callback routine was not releasing that parent image request. Fix that. The slab allocation stuff just added has greatly simplified the search for the source of this memory leak.
