Subject: [patch 073/158] mm/memory-failure.c: use page_shift() in add_to_kill()
Date: Sat, 30 Nov 2019 17:53:41 -0800 [thread overview]
Message-ID: <20191201015341.uq80Vd14O%akpm@linux-foundation.org> (raw)
From: Yunfeng Ye <yeyunfeng@huawei.com>
Subject: mm/memory-failure.c: use page_shift() in add_to_kill()
page_shift() is supported after the commit 94ad9338109f ("mm: introduce
page_shift()").
So replace with page_shift() in add_to_kill() for readability.
