FUTEX_PRIVATE_FLAG Can Reduce Same-Process Lock Overhead
The post says that in a multi-process system, futex waiters use a global kernel hash table. For threads sharing memory within one process, FUTEX_PRIVATE_FLAG tells the kernel to skip that shared hash.
This flag may reduce lock latency for synchronization between threads in the same process.
