    I don't think they're all that different conceptually. If something as
    simple as this was merged then we'd at least have a common structure to
    throw things in, and a common syscall infrastructure that can gracefully
    handle kernel API versioning without requiring dozens of syscalls.

    Please read "vx_info" as "container" (or your preferred term). I
    decided to punt on the naming issue and copy Herbert :-).

    And also because the acronym "vx" makes the API look nice, at least to
    mine and Herbert's eyes, then when you go to the network virtualisation
    you get "nx_info", etc. However I'm thinking any of these terms might
    also be right:

    - "vserver" spelt in full
    - family
    - container
    - jail
    - task_ns (sort for namespace)

    Perhaps we can get a ruling from core team on this one, as it's
    aesthetics :-).


    This patch is simple, but does not handle SMP scalability very well
    (you'll get a lot of cacheline problems when you start actually using
    the container structure; the hashing helps a lot there), and does not
    provide functions such as looking up a container by ID etc. I think
    Herbert's context.c is a pretty nice basic set of functions for dealing
    with container-like things.

    Thanks for your feedback!
