* Mutex queue head keeps the list of all userspace mutexes.
*
* Here, mutex_control_mutex is a single lock for:
* (1) Mutex_queue create/deletion
* (2) List add/removal.
* (3) Wait synchronization:
* - Both waitqueue spinlocks need to be acquired for
* rendezvous inspection to occur atomically. Currently
* it's not done since we rely on this mutex for that.
