Subject: [RFC][PATCH v1 01/11] mm: hwpoison: cleanup unused PageHuge() check
Date: Fri, 9 Nov 2018 15:47:05 +0900 [thread overview]
Message-ID: <1541746035-13408-2-git-send-email-n-horiguchi@ah.jp.nec.com> (raw)
In-Reply-To: <1541746035-13408-1-git-send-email-n-horiguchi@ah.jp.nec.com>
memory_failure() forks to memory_failure_hugetlb() for hugetlb pages,
so a PageHuge() check after the fork should not be necessary.
