Subject: Re: [PATCH v2] net: iterate online nodes in skb_defer_free_flush()
Date: Wed, 16 Sep 2026 07:53:35 +0800	[thread overview]
Message-ID: <20260915235335.3580993-1-kris.pan@intel.com> (raw)
In-Reply-To: <20260915164008.4f65ddc4@kernel.org>

Right, the node-offline race is real.  I'll fix it in a v3 so the flush
doesn't depend on node_online_map, e.g. a per-CPU mask of pending nodes
set by the producer and drained by the flush.

Thanks.
