Hi, all

         I have one question about __tl_lock. The current implementation of __tl_lock shown as follow.

Obviously __thread_list_lock is a private memory, why don’t we pass FUTEX_PRIVATE option to __wait?

```

void __tl_lock(void)

{

int tid = __pthread_self()->tid;

int val = __thread_list_lock;

if (val == tid) {

tl_lock_count++;

return;

}

while ((val = a_cas(&__thread_list_lock, 0, tid)))

__wait(&__thread_list_lock, &tl_lock_waiters, val, 0);

}

```

Thank you to explain.
