namespace filedescriptors

I have ripped out all of my work to wire up the syscalls and make that work properly.

Please think about pulling:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/linux-2.6-nsfd.git

The code really cleans up working with namespaces.

The killer feature is probably going to be that it becomes trivial to isolate a vpn connection into it's own network namespace, allowing all of the weirdness that comes with vpn connections to be isolated.

If nothing happens with this until the next merge cycle I will understand.

Eric W. Biederman (8):
ns: proc files for namespace naming policy.
ns: Introduce the setns syscall
ns proc: Add support for the network namespace.
ns proc: Add support for the uts namespace
ns proc: Add support for the ipc namespace
net: Allow setting the network namespace by fd
ns: Declare sys_setns in syscalls.h
ns proc: Return -ENOENT for a nonexistent /proc/self/ns/ entry.

Stephen Rothwell (1):
net: fix get_net_ns_by_fd for !CONFIG_NET_NS
