The helper gathers a folio order statistics of folios within a virtual
address range and checks it against a given order list. It aims to provide
a more precise folio order check instead of just checking the existence of
PMD folios.
The helper will be used the upcoming commit.

I tested this patch, and it works for me.

By the way, I moved gather_after_split_folio_orders() to the vm_util.c
file as a helper for mTHP collapse checks in my patchset[1]. I'm not
sure whether you need to move gather_after_split_folio_orders() to
vm_util.c in this patch, or if I should move it in my patchset.
