Subject: [PATCH] netns: fix ip_rt_frag_needed rt_is_expired
Running recent kernels, and using a particular vpn gateway, I've been
having to edit my mails down to get them accepted by the smtp server.
Git bisect led to commit e84f84f276473dcc673f360e8ff3203148bdf0e2 -
netns: place rt_genid into struct net. The conversion from a != test
to rt_is_expired() put one negative too many: and now my mail works.

Ingo was having strange distcc problems, might this help him too?
