Subject: [PATCH 4/4] mm/page_alloc.c: bad_[reason|flags] is not necessary when PageHWPoison
Date:   Sun, 19 Jan 2020 21:14:08 +0800
Message-Id: <20200119131408.23247-5-richardw.yang@linux.intel.com>
In-Reply-To: <20200119131408.23247-1-richardw.yang@linux.intel.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Since function returns directly, bad_[reason|flags] is not used any
where.

This is a following cleanup for commit e570f56cccd21 ("mm:
check_new_page_bad() directly returns in __PG_HWPOISON case")
