Perhaps a Fixes: tag might be helpful here, such as: Fixes: 96db776a3682 ("i40e/i40evf: fix interrupt affinity bug") as I reported in my other (late) patch: http://marc.info/?l=linux-netdev&m=150279303222066&w=2 > Cc: stable@vger.kernel.org and maybe also an indication about which versions this applies to, such as Cc: stable@vger.kernel.org # 4.10+ In general, feel free to copy from my commit message. These comments also apply to: [PATCH] net/i40evf: use cpumask_copy() for assigning cpumask Thanks, -- Stefano
