[libc-commits] [PATCH] D79828: [libc] Add implementation of call_once from threads.h.

[Fangrui Song via Phabricator via libc-commits]

MaskRay added a comment.

This is incorrect.

> Completion of an effective call to the call_once function synchronizes with all subsequent calls to the call_once function with the same value of flag.

Before the completion, the subsequent call should wait.
