What is needed is to flesh out what the kernel interface should looke like. I suggested a sysfs file for suspending and resuming access to the device, if people have other ideas they should voice them. > How do we go by making this script maybe more broad, or simple so that > it can be implemented on more devices? It's a test utility, I just wrote it so people could test. The actual command used woule be used in the internal implementation. The file itself holds no other value than for testing purposes. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
