Subject: [PATCH v2 3/3] mm: sparse: remove __section_nr() function
Date: Mon, 5 Jul 2021 17:55:38 +0900 [thread overview]
Message-ID: <20210705085538.14557-4-ohoono.kwon@samsung.com> (raw)
In-Reply-To: <20210705085538.14557-1-ohoono.kwon@samsung.com>
As the last users of __section_nr() are gone, let's remove unused
function __section_nr().
