Subject: [RFC 2/6] drm/i915: Restrict sentinel requests further
Date: Fri, 12 Mar 2021 15:46:18 +0000	[thread overview]
Message-ID: <20210312154622.1767865-3-tvrtko.ursulin@linux.intel.com> (raw)
In-Reply-To: <20210312154622.1767865-1-tvrtko.ursulin@linux.intel.com>

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

Disallow sentinel requests follow previous sentinels to make request
cancellation work better when faced with a chain of requests which have
all been marked as in error.
