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 [thread overview]
Message-ID: <20200119131408.23247-5-richardw.yang@linux.intel.com> (raw)
In-Reply-To: <20200119131408.23247-1-richardw.yang@linux.intel.com>
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")
