WTF: patch "[PATCH] qla2xxx: Abort stale cmds on qla_tgt_wq when plogi arrives" was seriously submitted to be applied to the 4.1-stable tree?

[<gregkh@linuxfoundation.org>]

The patch below was submitted to be applied to the 4.1-stable tree.

I fail to see how this patch meets the stable kernel rules as found at
Documentation/stable_kernel_rules.txt.

I could be totally wrong, and if so, please respond to 
<stable@vger.kernel.org> and let me know why this patch should be
applied.  Otherwise, it is now dropped from my patch queues, never to be
seen again.

thanks,

greg k-h
