Subject: [PATCH v5 06/16] mm,hwpoison: Un-export get_hwpoison_page and make it static
Date: Fri, 31 Jul 2020 12:21:02 +0000	[thread overview]
Message-ID: <20200731122112.11263-7-nao.horiguchi@gmail.com> (raw)
In-Reply-To: <20200731122112.11263-1-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.
