MySQL Table Lock Queue Check Optimization

Application scenario: MySQL OLTP with high-concurrency read/write operations

Technical principle: A more direct status check mechanism is added to the table lock queue, so that the system can first determine whether there are any table lock types in the queue that conflict with the intent lock. For scenarios where LOCK_S or LOCK_X does not exist, unnecessary queue traversal can be skipped, allowing the compatibility check to be completed directly.

Performance metric: The sysbench write-only performance is improved by 5%.
