Subject: [PATCH v2 05/21] mm/memcontrol: remove CONFIG_SLAB #ifdef guards
Date: Mon, 20 Nov 2023 19:34:16 +0100	[thread overview]
Message-ID: <20231120-slab-remove-slab-v2-5-9c9c70177183@suse.cz> (raw)
In-Reply-To: <20231120-slab-remove-slab-v2-0-9c9c70177183@suse.cz>

With SLAB removed, these are never true anymore so we can clean up.
