I don't think either of those are acceptable, and both are to me
*much* worse than the existing "fetch_and_zero()" that i915 uses.

That name just makes sense and explains what it does. There is no ambiguity.

I will not be taking a pull that makes a good name worse.

Naming matters, and "use a generic function" is not an excuse for
having bad names.
