Subject: [PATCH] mm/hugetlb: use helper huge_page_size() to simplify the hugetlb_vm_op_pagesize()
Date: Fri, 5 Feb 2021 04:22:09 -0500 [thread overview]
Message-ID: <20210205092209.16024-1-linmiaohe@huawei.com> (raw)
We can use helper huge_page_size() to get the size of the pages allocated
when backing a VMA directly to make the code more simplified.
