ide: use per-device request queue locks (v2)
* Move hack for flush requests from choose_drive() to do_ide_request(). * Add ide_plug_device() helper and convert core IDE code from using per-hwgroup lock as a request lock to use the ->queue_lock instead. * Remove no longer needed: - choose_drive() function - WAKEUP() macro - 'sleeping' flag from ide_hwif_t - 'service_{start,time}' fields from ide_drive_t This patch results in much simpler and more maintainable code (besides being a scalability improvement). v2: * Fixes/improvements based on review from Elias: - take as many requests off the queue as possible - remove now redundant BUG_ON() Cc: Elias Oltmanns <eo@nebensachen.de> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
