Subject: [PATCH v1 5/9] mm: soft-offline: dissolve free hugepage if soft-offlined
Date: Thu,  1 Jun 2017 17:16:55 +0900	[thread overview]
Message-ID: <1496305019-5493-6-git-send-email-n-horiguchi@ah.jp.nec.com> (raw)
In-Reply-To: <1496305019-5493-1-git-send-email-n-horiguchi@ah.jp.nec.com>

Now we have code to rescue most of healthy pages from a hwpoisoned
hugepage.  So let's apply it to soft_offline_free_page too.
