But it makes review harder because your patch is removing irq_work,
*nothing* in the commit message is talking about *why* you're doing
that additional change. I'd imagine at the end of the commit message
something like:

"While at it, repurpose the IRQ work callback into a function which
concentrates the NMI duration checking."

This lets a reader know know why that additional change is done instead
of going back'n'forth and having to ask you why you're doing this.

Ok?
