[PATCH] drm/i915: Drop i915_request.i915 backpointer

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



We infrequently use the direct i915 backpointer from the i915_request,
so do we really need to waste the space in the struct for it? 8 bytes
from the most frequently allocated struct vs an 3 bytes and pointer
chasing in using rq->engine->i915?
