Typecasting a void pointer to unsigned long in zsmalloc.c

Yeah this definitely seems more high priority currently. Is there
anything outside people can do, to help the effort?

You're probably right, come to think of it now maybe describing all of
these details in kernelnewbies isn't appropriate.

What my concern with documentation usually is, when it's hard to
navigate or when fundamental information is missing or is spread
outside of the documentation, it becomes really discouraging to engage
with a project, especially for new people.

I'll look into what's missing, if anything, at kernel.org regarding
data types and attempt to send a patch for the docs there, when I have
the time.

I didn't even know about this one.

This makes sense, I guess I interpreted it more as a small summary of
kernel.org, but helping people find the facts is the more practical
solution. There's definitely no way to keep track of everything
happening and updating it constantly, now that I think of it.
