Will do.

I don't have good links for them yet because both of them are still not in
upstream man-page project.  Even THP version of MADV_COLLAPSE man page just
got added into the man-page repository in Nov 2022 so most of the websites
that host man pages won't even have MADV_COLLAPSE..

For now I'll add some more paragraphs trying to explain everything, and
I'll also link to madvise(2) where both of them will be discussed in the
future.

Thanks,
