When compound pages are enabled, although the mm layer still returns an array of page pointers, a subset (or all) of them may have the same page head since a max 180kb skb can span 2 hugepages if it is on the boundary, be a mix of pages and 1 hugepage, or fit completely in a hugepage. Instead of referencing page head on all page pointers, use page length arithmetic to only call page head when referencing a known different page head to avoid touching a cold cacheline.

You are awesome, thank you!
