It's not new.
I just moved it:
previously:
	if(cond) {
		do {}
		 while()
	} else {return}

now:
	if (!cond)
		return;
	do {}
	while {}

Also this moves a consume_skb() from a path protected by spin locks.

As far as I understand it, the spin locks protect the hslot, and freeing the 
skb does not walk/change or interact with the hslot in any way.
