It's an exported-to-modules library function.  It should be documented,
please?  The page-frag API is only partially documented, but that's no
excuse.

Okay.  I assume you want the documentation as a follow-up patch since
I received a notice that the patch was added to -mm?

Yes please.  Or a replacement patch which I'll temporarily turn into a
delta, either is fine.

If you would like I could look at doing a couple of renaming patches
so that we make the API a bit more consistent.  I could move the
__alloc and __free to what you have suggested, and then take a look at
trying to rename the refill/drain to be a bit more consistent in terms
of what they are supposed to work on and how they are supposed to be
used.

I think that would be better - it's hardly high-priority but a bit of
attention to the documentation and naming conventions would help tidy
things up.  When you can't find anything else to do ;)
