You are essentially reverting commit 7d8faaf15545 which adds the
hpage_collapse_ prefix. Since in the next patch you also unify
madvise and khugepaged, removing hpage_collapse prefix would
make sense, but then I tend to agree with Liam that dropping
the prefix altogether is better. Having all the functions in
khugepaged.c prefixed with khugepaged_ seems unnecessary work.

@David, I forgot where you replied but I remember you saying
that we should not introduce MADV_COLLAPSE mTHP support for
now?
