From 7f4b6065d9a842721a04632fc219aa453d1b2f5c Mon Sep 17 00:00:00 2001 From: Fan Ni Date: Mon, 5 May 2025 11:22:43 -0700 Subject: mm/hugetlb: refactor __unmap_hugepage_range() to take folio instead of page The function __unmap_hugepage_range() has two kinds of users: 1) unmap_hugepage_range(), which passes in the head page of a folio. Since unmap_hugepage_range() already takes folio and there are no other uses of the folio struct in the function, it is natural for __unmap_hugepage_range() to take folio also. 2) All other uses, which pass in NULL pointer. In both cases, we can pass in folio. Refactor __unmap_hugepage_range() to take folio.
