SHOW ENGINE INNODB MUTEX functionality is completely removed, as are the InnoDB latching order checks. We will enforce innodb_fatal_semaphore_wait_threshold only for dict_sys.mutex and lock_sys.mutex. dict_sys_t::mutex_lock(): A single entry point for dict_sys.mutex. lock_sys_t::mutex_lock(): A single entry point for lock_sys.mutex. FIXME: srv_sys should be removed altogether; it is duplicating tpool functionality. fil_crypt_threads_init(): To prevent SAFE_MUTEX warnings, we must not hold fil_system.mutex. fil_close_all_files(): To prevent SAFE_MUTEX warnings for fil_space_destroy_crypt_data(), we must not hold fil_system.mutex while invoking fil_space_free_low() on a detached tablespace.
