Mmm, actually it is a whole changeset and should go as a one patch. I didn't find it to be big and my review took only 5-10mins..Cleanup of dev_base list use, with the aim to make device list per-namespace.
In almost every occasion, use of dev_base variable and dev->next pointer
could be easily replaced by for_each_netdev loop.
A few most complicated places were converted to using
first_netdev()/next_netdev().
As a proof of concept patch this is ok.
As a real world patch this is much too big, which prevents review.
Plus it takes a few actions that are more than replace just
iterators through the device list.
