There's a new problem with the code that tried to solve the SMP io-request
spinlock problems. In particular, "unplug_device()" used to call in to the
device driver with interrupts disabled, the new version has moved it to
outside the interrupt disabled region. That might result in some nasty
re-entrancy issues.
Ingo, would you think about this? I agree with your change wrt the
io_request_lock, but it definitely looks a bit fishy wrt this.
