It's a _damn_ good point, but I see we went ahead and merged sys_epoll_pwait without it anyway -- despite the fact that it's include/linux/eventpoll.h which contains the example of why we should think first :) I think I even threw together an untested implementation of compat_sys_epoll_pwait() at one point to assist with that task, but it didn't seem to help much. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
