namespace attach (setns) patches

[Serge Hallyn]

Hi,

In addition to the user namespace patchset (the first part of which
is now in linux-next) we'd also like the remaining setns patches
to be considered for the quantal kernel.  There are two namespaces
(beside user) which are not yet exported through /proc/self/ns/ ,
mnt and pid.  The mnt attach patchset has been recently sent and
acked, but the online linux-kernel archives seem to all be missing
it.  The ack is here:

http://www.spinics.net/lists/linux-fsdevel/msg55150.html

For the pid namespace, an older version of the patchset is here:
http://git.kernel.org/?p=linux/kernel/git/ebiederm/linux-namespace-control-devel.git;a=summary

But Eric is trying to fix some long-standing pidns bugs in the same
set, so doesn't have a new set ready.

I'm just sending these links (at apw's request at UDS) so you can
gauge the complexity.

I can explictly forward the mntns patches if you like (and don't
mind the noise).

thanks,
