Subject: [PATCH 0/5] Make nicer CONFIG_NET_NS=n case code
Date: Wed, 31 Oct 2007 22:19:43 +0300 [thread overview]
Message-ID: <4728D54F.2080208@openvz.org> (raw)
Currently we have the NET_NS config option, but the only change it
makes is just return ERR_PTR(-EINVAL) inside the cloning call thus
introducing a bunch of a dead code and making the reference counting
unneeded. This is not very good.
So clean the net_namespace.c to fix this.
I have sent a set of patches to Andrew to make similar thing for
other namespaces, which introduces the NAMESPACES option to turn
all the namespaces off at once (to make embedded people suffer
less). So after that stuff is in, there will be some more patches
to tie all this together.
What is to be done after this set is to make the register_pernet_xxx
stuff smaller. Currently this code weights approximately 500 bytes,
so it worths reducing it, but I haven't found a good solution yet.
