See my email at

  https://lore.kernel.org/all/CAHk-=wiacQM76xec=Hr7cLchVZ8Mo9VDHmXRJzJ_EX4sOsApEA@mail.gmail.com/

for what I think is the way forward if we want to do new defines and
clean up the situation.

It's really just an example (and converts two list cases and one
single file that uses them), so it's not in any way complete.

I also has that "-std=gnu11" in the patch so that you can use the
loop-declared variables - but without the other small fixups for some
of the things that exposed.

I'll merge the proper version of the "update C standard version" from
Arnd early in the 5.18 merge window, but for testing that one file
example change I sent out the patch like that.
