Subject: [NETNS][RAW]: Create the /proc/net/raw(6) in each namespace.
X-Git-Tag: v2.6.25-rc1~1162^2~753
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a308da1627d711fd0c7542bfe892abc78d65d215;p=linux-2.6

[NETNS][RAW]: Create the /proc/net/raw(6) in each namespace.

To do so, just register the proper subsystem and create files in
->init callbacks.

No other special per-namespace handling for raw sockets is required.
