Some shrinker add lock in count_objects() may cause lock contention issues and lead all task stall on slab shrink. Add vendor hook in do_shrink_slab() for shrinker->count_objects() latency measuring. Add 3 oem data in shrink_control struct. Two is for shrinker->count_objects() and shrinker->scan_objects() latency measuring, other one to store priority, some shrinker know the reclaimer priority can control the memory reclaim more better.
