Subject: [CI 09/21] drm/i915: Expand bool interruptible to pass flags to i915_wait_request()
Date: Fri,  9 Sep 2016 12:00:49 +0100	[thread overview]
Message-ID: <20160909110101.31967-9-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20160909110101.31967-1-chris@chris-wilson.co.uk>

We need finer control over wakeup behaviour during i915_wait_request(),
so expand the current bool interruptible to a bitmask.
