Subject: [PATCH v17 01/20] drm/msm: Remove dangling submitqueue references
Date: Sat, 5 Sep 2020 13:04:07 -0700 [thread overview]
Message-ID: <20200905200454.240929-2-robdclark@gmail.com> (raw)
In-Reply-To: <20200905200454.240929-1-robdclark@gmail.com>
From: Rob Clark <robdclark@chromium.org>
Currently it doesn't matter, since we free the ctx immediately. But
when we start refcnt'ing the ctx, we don't want old dangling list
entries to hang around.
