Subject: Re: [PATCH net-next] net: em_canid: remove useless statements from
 em_canid_change

This is right for the first set of filters that is ever configured in
em_canid_change().

But what happens in an update case?
Does is turn the cm_old reference to a memory leak then?

Or do we always get a brand new "struct tcf_ematch *m" here??

Oliver
