Subject: [PATCH v2 10/22] slab: Remove folio references from ___kmalloc_large_node()
Date: Wed, 10 Sep 2025 12:54:52 +0100 [thread overview]
Message-ID: <20250910115507.1991829-11-willy@infradead.org> (raw)
In-Reply-To: <20250910115507.1991829-1-willy@infradead.org>
There's no need to use folio APIs here; just use a page directly.
