Chris Wilson 922d369b29 drm/i915/gt: Clear the buffer pool age before use ... If we create a new node, it is possible for the slab allocator to return us a recently freed node. If that node was just retired, it will retain the current jiffy as its node->age. There is then a miniscule window, where as that node is retired, it will appear on the free list with an incorrect age and be eligible for reuse by one thread, and then by a second thread as the correct node->age is written.
