    Subject[07/26] drm/i915: Fix object refcount leak on mmappable size limit error path.
    3.1-stable review patch.  If anyone has any objections, please let me know.


    From: Eric Anholt <>

    commit 14660ccd599dc7bd6ecef17408bd76dc853f9b77 upstream.

    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.
