Message-ID: <1181473295.466bda0f80347@webmail.ics.forth.gr> Date: Sun, 10 Jun 2007 14:01:35 +0300 From: mcatos@....forth.gr To: linux-kernel@...r.kernel.org Subject: Block device request queue processing question I am developing a stacking block driver and so far the driver was accepting requests using the 'make_request' function (without a queue). When I switched to using a request queue, I noticed that the driver received much more reuquests in a single call, which is very good for me. The problem is that the driver must initiate I/O towards the physical device, which cannot be done inside the function that services the requests. Is there a way I can process all the request in a context where sleeping is permitted? I tried to dequeue all the requests using 'blkdev_dequeue_request' but I do not know how to properly handle request completion. Thanx in advance. ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
