请问 OWST 相关 commit 或 patch 有吗？ #99

Closed dibingfa closed 2 months ago

GC线程调度优化 Optimized Work Stealing Threads 开启方式：默认开启，在启动参数里面显示添加 -XX:-UseOWSTTaskTerminator关闭 原理：GC并行线程通过Work Stealing进行负载均衡，减少GC停顿时间。原有Work Stealing算法中所有空闲GC线程都会频繁尝试work stealing造成CPU资源浪费，新算法采用一个master线程监控是否进行work stealing并在适当时机唤醒其它空闲GC线程，极大减少CPU资源浪费和进程间的CPU资源竞争。OWST在OpenJDK社区版本12以后支持，大数据Hibench测试有最多30%的性能提升，平均提升8%。

请问这个功能相关 commit 或 patch 可以定位下不？想学习下。
