Looks like enough to me. (Probably it could even share space with
the state.)

So I made some progress on this, three things:

1) I remember why I choose a to use a bit in my design, it's so that
   it does not increase the costs of the checks in the fast paths.
   test_bit(X) && test_bit(Y) can be combined into a single test by
   the compiler.

Except for the braindead volatile that gets stuck on the bitops pointer.

Last time I complained about this, a lot of noise was made and I think
Linus wanted it to stay around so we could pass volatile pointers to
bitops & co without warnings. I say we should just remove the volatile
and kill any callers that might warn...
