Minor synchronisation quibble in scsifront
I''ve been having a look through scsifront again, and I saw this bit: ring_req->timeout_per_command = (sc->timeout_per_command / HZ); ring_req->nr_segments = 0; spin_unlock_irq(host->host_lock); scsifront_do_request(info); wait_event_interruptible(info->shadow[ring_req->rqid].wq_reset, info->shadow[ring_req->rqid].wait_reset); in scsifront_dev_reset_handler(). Looking at scsifront_do_request(): static void scsifront_do_request(struct vscsifrnt_info *info) { struct vscsiif_front_ring *ring = &(info->ring); unsi...
