From a25fddced835ae53d18eb4bddabd719b4cebf624 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Wed, 24 Feb 2021 12:10:14 -0800 Subject: hugetlbfs: make hugepage size conversion more readable The calculation 1U << (h->order + PAGE_SHIFT - 10) is actually equal to (PAGE_SHIFT << (h->order)) >> 10. So we can make it more readable by replace it with huge_page_size(h) >> 10.
