Subject: [PATCH 3/8] drm/msm: Clear msm_obj->sgt in put_pages()
Date: Mon, 5 Apr 2021 10:45:26 -0700 [thread overview]
Message-ID: <20210405174532.1441497-4-robdclark@gmail.com> (raw)
In-Reply-To: <20210405174532.1441497-1-robdclark@gmail.com>
From: Rob Clark <robdclark@chromium.org>
Currently this doesn't matter since we keep the pages pinned until the
object is destroyed. But when we start unpinning pages to allow objects
to be evicted to swap, it will.
