Hello,
this adds a bio write queue congestion control to the pktcdvd driver with fixed on/off marks. It prevents that the driver consumes a unlimited amount of write requests.
Needs this patch named: [PATCH 1/2] 2.6.19-rc2-mm1 ll_rw_blk.c: export clear_queue_congested and set_queue_congested
I hope this code is ok now ;) (Maybe the surrounding spin_locks can be removed, but for atomic access to bio_write_size etc., they may be a good thing...)
