<chris@chris-wilson.co.uk> Date: Mon Mar 4 11:41:13 2019 +0000 drm/i915: Acquire breadcrumb ref before cancelling We may race the interrupt signaling with retirement, in which case the order in which we acquire the reference inside the interrupt is vital to provide the correct barrier against the request being freed in retirement, i.e. we need to acquire our reference before marking the breadcrumb as cancelled (as soon as the breadcrumb is cancelled retirement may drop its reference to the request without serialisation with the interrupt handler). <3>[ 683.372226] BUG i915_request (Tainted: G U
