    SHOW ENGINE INNODB MUTEX shows all mutexes and rw_locks. This can
    be overwhelming particularly when the buffer pool is very large
    (note that each block in buffer pool has at least one mutex, one
    rw_lock and an additional mutex if rw_lock does not use atomics).
    With this patch status of following mutexes and rw-locks is not shown:
    
    1) block->mutex
    2) block->lock
    3) block->lock->mutex (if applicable)
    4) All other mutexes and rw-locks for which number of os-waits are zero
