static key arrays?

[Johannes Berg]

Hi Peter, Jason, all,

Per the recent type-safe API changes, it's no longer easy to generate
an array of static keys. I was planning to do that for a set of very
unlikely debug options.

It sounds like you're planning to remove the previous API entirely at
some point, so I'm wondering if you've given any thought to this
possibility.

I briefly played with the idea of adding a macro for that, but the
necessary "REPEAT(n, d)" macro for the initialisation becomes ugly
pretty quickly and, afaict, needs to have enough macros for the maximum
expected numbers.

For the case I was looking at it's static_key_false so a zero
-initialized array would be sufficient, but that can't be done easily
with a static_key_true.
