@arigo: Technically we also need that the writes to memory are observed to happen-before the write() call on the wakeup fd, which is not something that Intel is going to make any guarantees about. But *probably* this is also safe because the kernel has to use some kind of cross-CPU synchronization to wake up the read()ing thread, and that imposes a memory barrier. |
