Subject: [PATCH v3 05/17] slab: Remove folio references from ___kmalloc_large_node()
Date: Fri, 24 Oct 2025 21:44:20 +0100	[thread overview]
Message-ID: <20251024204434.2461319-6-willy@infradead.org> (raw)
In-Reply-To: <20251024204434.2461319-1-willy@infradead.org>

There's no need to use folio APIs here; just use a page directly.
