Userspace would have to tell the kernel which set of devices is available. (In your example: The set consists of m1 and m2; but does not include m0 nor m3 nor m6391.) So instead of telling the kernel beforehand what to enqueue for registration and in which order to enqueue it, we simply let userspace give persistent alias names to devices after the fact. -- Stefan Richter -=====-=-=== -=-= -=--- http://arcgraph.de/sr/ - 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/
