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. Tested-by: Baolin Wang baolin.wang@linux.alibaba.com
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.
