IPVS: fix netns if reading ip_vs_* procfs entries
Hans Schillstrom [Sun, 15 May 2011 15:20:29 +0000 (17:20 +0200)]
Without this patch every access to ip_vs in procfs will increase
the netns count i.e. an unbalanced get_net()/put_net().
(ipvsadm commands also use procfs.)
The result is you can't exit a netns if reading ip_vs_* procfs entries.
