Subject: [PATCH 14/40] mm: numa: split_huge_page: transfer the NUMA type from the pmd to the pte
Date: Thu, 22 Nov 2012 19:25:27 +0000 [thread overview]
Message-ID: <1353612353-1576-15-git-send-email-mgorman@suse.de> (raw)
In-Reply-To: <1353612353-1576-1-git-send-email-mgorman@suse.de>
From: Andrea Arcangeli <aarcange@redhat.com>
When we split a transparent hugepage, transfer the NUMA type from the
pmd to the pte if needed.
