Looks certainly attractive to me. Nice small patch. How quickly after the death of the process is proc_pid_flush() called?
If this could go in and the futex stuff is handled, there is "only" async I/O to handle. After that we could finally create a uniform event mechanism at userlevel which binds all these events (I/O, process/thread termination, sync primitives) together. Maybe support for legacy sync primitives (SysV semaphores, msg queues) is needed as well, don't know yet. Note that I assume that polling of POSIX mqueues works as it did the last time I tried it. - 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/
