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()
