Subject: [Intel-gfx] [PATCH 3/6] drm/i915: Handle async cancellation in sentinel assert
Date: Tue, 16 Mar 2021 16:23:23 +0000	[thread overview]
Message-ID: <20210316162326.1994039-4-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20210316162326.1994039-1-tvrtko.ursulin@linux.intel.com>

From: Tvrtko Ursulin <tvrtko.ursulin@intel.com>

With the watchdog cancelling requests asynchronously to preempt-to-busy we
need to relax one assert making it apply only to requests not in error.
