The net tree can take fixes anytime, so if you target this patch to
[PATCH net] this speeds up integration into mainline kernels. Note, as
soon as this patch hits Linus tree, we can request -stable submission
so older -stable kernels can get this.

If this follows the net-next path, then this fix is going to take
several weeks (sometimes months) to show in mainline kernels.

So please add [PATCH net] or [PATCH net-next] so it's clear to
everyone what is your target, David usually requests this.

BTW, probably you can target this small fix to net, then you can
request David to pull net into net-next so the fix propagates onwards.

Sorry for this bureaucratic stuff, but given the workload we deal
with, you will really helps us if you deal with these nitpicks.

Thanks Andreas!
