[patch to drivers/scsi/sd.c snipped]
It turns out that patch isn't necessary - all that was needed is to do
spin_lock_irqsave(&io_request_lock, flags) before calling the scsi
done function in the mesh driver (and spin_unlock_irqrestore after).
That's done, in different forms, both in vger and Linus' 2.2.0-pre2
and later, so it should be OK now.
Paul.
