Adam Rutkowski	d91012f4b4	Introduce hash bucket locks ... There is one RW lock per hash bucket. Write lock is required to map cacheline, read lock is sufficient for traversing. Hash bucket locks are always acquired under global metadata read lock. This assures mutual exclusion with eviction and management paths, where global metadata write lock is held.
