Subject: [PATCH v4 01/15] mm,hwpoison: cleanup unused PageHuge() check
Date: Thu, 16 Jul 2020 14:37:55 +0200	[thread overview]
Message-ID: <20200716123810.25292-2-osalvador@suse.de> (raw)
In-Reply-To: <20200716123810.25292-1-osalvador@suse.de>

From: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com>

Drop the PageHuge check since memory_failure forks into memory_failure_hugetlb()
for hugetlb pages.
