Subject: [PATCH v3 06/15] mm,hwpoison: Un-export get_hwpoison_page and make it static
Date: Wed, 24 Jun 2020 15:01:28 +0000
Message-ID: <20200624150137.7052-7-nao.horiguchi@gmail.com> (raw)
In-Reply-To: <20200624150137.7052-1-nao.horiguchi@gmail.com>

From: Oscar Salvador <osalvador@suse.de>

Since get_hwpoison_page is only used in memory-failure code now,
let us un-export it and make it private to that code.
