Subject: [PATCH v4 06/15] mm,hwpoison: Un-export get_hwpoison_page and make it static
Date: Thu, 16 Jul 2020 14:38:00 +0200	[thread overview]
Message-ID: <20200716123810.25292-7-osalvador@suse.de> (raw)
In-Reply-To: <20200716123810.25292-1-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.
