Subject: [PATCH net-next v2 1/2] mm/slab: add a node-track-caller variant for kmem buckets allocation
Date: Thu, 11 Jun 2026 13:46:41 +0100	[thread overview]
Message-ID: <20260611124642.345400-2-pfalcato@suse.de> (raw)
In-Reply-To: <20260611124642.345400-1-pfalcato@suse.de>

This is required by users that want to use kmem buckets, but still
desire specifying the NUMA node.
