Subject: [PATCH] dma-buf: fix reservation_object_wait_timeout_rcu to wait correctly
Date: Fri, 21 Jul 2017 18:20:01 +0200 [thread overview]
Message-ID: <1500654001-20899-1-git-send-email-deathsimple@vodafone.de> (raw)
From: Christian König <christian.koenig@amd.com>
With hardware resets in mind it is possible that all shared fences are
signaled, but the exlusive isn't. Fix waiting for everything in this situation.
