Subject: IPVS: fix netns if reading ip_vs_* procfs entries
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0f08190fe8af3cdb6ba19690eb0fa253ecef4bde;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

IPVS: fix netns if reading ip_vs_* procfs entries

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.
