head = &q->queue_head is a simple offset calculation in the request
queue structure. Moving this into the spinlock won't change anything,
since q->queue_head isn't a pointer that can change.
Independent of that I can second the observation that test11 can corrupt
ext2 in memory. I think that this is related to the memory management
problems I see but I can't prove it yet.
