From 14660ccd599dc7bd6ecef17408bd76dc853f9b77 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 31 Oct 2011 23:16:21 -0700 Subject: [PATCH] drm/i915: Fix object refcount leak on mmappable size limit error path. I've been seeing memory leaks on my system in the form of large (300-400MB) GEM objects created by now-dead processes laying around clogging up memory. I usually notice when it gets to about 1.2GB of them. Hopefully this clears up the issue, but I just found this bug by inspection.
