Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit X-Hops: 1 X-Originating-Heisenberg-IP: [82.68.23.174] Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org The HDAPS (IBM ThinkPad Hard Disk Active Protection System) project currently has working code to read the accelerometer data, and to park the hard disk. However, we're going to need a way to keep the disk idle following the park command, as any subsequent command reaching the disk may reactivate the drive before it's safe to resume. Is there any mechanism available in the kernel to 'freeze' the i/o queue? Thanks, Jon. ______________________________________________________________ Email via Mailtraq4Free from Enstar (www.mailtraqdirect.co.uk)
