Zqiang 8f556a326c locking/rtmutex: Fix incorrect condition in rtmutex_spin_on_owner() ... Optimistic spinning needs to be terminated when the spinning waiter is not longer the top waiter on the lock, but the condition is negated. It terminates if the waiter is the top waiter, which is defeating the whole purpose.
