Subject: [RFC 01/11] drm/i915/scheduler: Remember request priority throughout its lifetime
Date: Thu, 23 Feb 2017 20:08:23 +0100	[thread overview]
Message-ID: <20170223190833.2888-2-michal.winiarski@intel.com> (raw)
In-Reply-To: <20170223190833.2888-1-michal.winiarski@intel.com>

Since request can be cancelled, we need to avoid overriding its priority
during submission to be able to resubmit it.
