-    drm/i915: Only clear the GPU domains upon a successful finish
-    
-    By clearing the GPU read domains before waiting upon the buffer, we run
-    the risk of the wait being interrupted and the domains prematurely
-    cleared. The next time we attempt to wait upon the buffer (after
-    userspace handles the signal), we believe that the buffer is idle and so
-    skip the wait.
-    
-    There are a number of bugs across all generations which show signs of an
-    overly haste reuse of active buffers.
-    
-    Such as:

-      https://bugs.freedesktop.org/show_bug.cgi?id=35863
-      https://bugs.freedesktop.org/show_bug.cgi?id=38952
-      https://bugs.freedesktop.org/show_bug.cgi?id=40282
-      https://bugs.freedesktop.org/show_bug.cgi?id=41098
-      https://bugs.freedesktop.org/show_bug.cgi?id=41102
-      https://bugs.freedesktop.org/show_bug.cgi?id=41284
-      https://bugs.freedesktop.org/show_bug.cgi?id=42141
-    
-    A couple of those pre-date i915_gem_object_finish_gpu(), so may be
-    unrelated (such as a wild write from a userspace command buffer), but
-    this does look like a convincing cause for most of those bugs.
