[PATCH 097/190] drm/i915/shrinker: Flush active on objects before counting

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

 



As we inspect obj->active to decide how many objects we can shrink (we
only shrink idle objects), it helps to flush the active lists first
in order to have a more accurate count of available objects.
