Subject: [PATCH 10/22] slab: Remove folio references from ___kmalloc_large_node()
Date: Fri, 29 Aug 2025 16:47:14 +0100	[thread overview]
Message-ID: <20250829154728.3397606-11-willy@infradead.org> (raw)
In-Reply-To: <20250829154728.3397606-1-willy@infradead.org>

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