From e87340ca5c9cecc8a11daf1a2dcabf23f06a4e10 Mon Sep 17 00:00:00 2001 From: ZhangPeng Date: Mon, 10 Apr 2023 21:39:29 +0800 Subject: userfaultfd: convert copy_huge_page_from_user() to copy_folio_from_user() Replace copy_huge_page_from_user() with copy_folio_from_user(). copy_folio_from_user() does the same as copy_huge_page_from_user(), but takes in a folio instead of a page. Convert page_kaddr to kaddr in copy_folio_from_user() to do indenting cleanup.
