Date: Mon, 20 Jul 2020 14:26:21 +0800 From: Baoquan He <bhe@...hat.com> To: linux-kernel@...r.kernel.org Cc: linux-mm@...ck.org, mike.kravetz@...cle.com, akpm@...ux-foundation.org, bhe@...hat.com Subject: [PATCH 3/5] mm/hugetlb.c: Remove the unnecessary non_swap_entry() The checking is_migration_entry() and is_hwpoison_entry() are stricter than non_swap_entry(), means they have covered the conditional check which non_swap_entry() is doing. Hence remove the unnecessary non_swap_entry() in is_hugetlb_entry_migration() and is_hugetlb_entry_hwpoisoned() to simplify code.
