Subject: regression (4.10) - interface remove uevents not generated

Hello,

It seems that commit 002d8a1a6c11b9b2a8ac615095589111dd52749b ("net:
skip genenerating uevents for network namespaces that are exiting")
broke 'remove' uevents for *all* network interfaces, even for those in
the main/default namespace.

Other than breaking some of my udev rules, this also causes problems for
NetworkManager, which apparently relies on those uevents to update its
interface information cache. (I ended up reverting that commit locally
just so I could connect to VPNs again.)

This problem is present in both v4.10.1 and current master
(v4.11-rc1-290-g434fd6353b4c).
