Wouldn't it have been better when Jiri would also see your reply? Now he isn't 
even aware of your criticism.

Interesting, I don't see it this way. This patch [0] is for netdev and we have 
the statement that "usage of sysfs in netdev subsystem is frowned upon". Now 
you want that we ignore that and than maybe Simon have to deal with the 
fallout when he forwards it to David?

Kind regards,
