I find it obnoxious that these are NOT REAL PROBLEMS.

It's KCSAN that is broken and doesn't allow us to just tell it to
sanely ignore things.

I don't want to add stupid and pointless annotations for a broken tooling.

Can you instead just ask the KCSAN people to have some mode where we
can annotate a pointer as a "use one or the other", and just shut that
thing up that way?

Because no, we're not adding some idiotic "f_op()" wrapper just to
shut KCSAN up about a non-issue.
