Well, maybe not *blind* sharing. But something more than the disconnect threads currently have with current->ioprio. Today an existing kernel thread would most certainly ignore a sys_ioprio_set() in the submitter and then handle an aio syscall with an old current->ioprio. Something more smart than that is all I'm on about. - z - 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/
