Subject: [PATCH v2 5/5] drm/i915: Revoke any shmemfs mappings on shrinking
Date: Wed, 24 May 2017 15:39:41 +0100 [thread overview]
Message-ID: <20170524143941.10989-5-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20170524143941.10989-1-chris@chris-wilson.co.uk>
When trying to shrink our buffers, also revoke any existing mappings
(forcing them to be faulted again on reuse) to improve the likelihood of
us being able to pageout the buffer.
