Subject: [PATCH v2 11/13] mm/sparse: remove flags parameter from sparse_init_one_section()
Date: Mon, 21 Sep 2026 21:59:03 +0200 [thread overview]
Message-ID: <20260921-b4-sparsemem_cleanups-v2-11-54d81d65e125@kernel.org> (raw)
In-Reply-To: <20260921-b4-sparsemem_cleanups-v2-0-54d81d65e125@kernel.org>
The last user of the flags parameter that used to pass SECTION_IS_EARLY
was removed, so let's remove the parameter.
Acked-by: Oscar Salvador <osalvador@suse.de>
