Why I'm doing:

What I'm doing:

noWaiters indicates whether there are other waiters. This will determine whether the lock can be directly acquired. If there are other waiters, the current locker cannot jump in line to acquire the lock first. A special scenario is to notify waiters in the existing wait list during release. At this time, the wait list needs to be ignored and as many waiters as possible need to be awakened.
Fixes #54923
