Subject: [PATCH] mm/hugetlb: Remove redundant VM_BUG_ON_PAGE on putback_active_hugepage()
Date: Mon, 8 Feb 2021 03:37:39 -0500 [thread overview]
Message-ID: <20210208083739.33178-1-linmiaohe@huawei.com> (raw)
PageHead(page) is implicitly checked in set_page_huge_active() via the
PageHeadHuge(page) check. So remove this explicit one.
