Actually these irq on/off lines are not part of my patch; they are
introduced by patch 05/10 on top of which my patches were rebased.

Nevertheless I agree with you - the kfifo migration patch should not
affect that irq on/off behavior. It's probably just a rebase gotcha.

But now that you point me to this irq on/off thing, it looks a bit
broken in terms of multiple concurrent mbox support since it relies on
a global rq_full state. I guess it'd be better to hold that rq_full
state in the relevant mbox queue state itself.

Fernando what do you think ?

Thanks,
Ohad.
