Subject: nfsd changes for 3.8

Please pull nfsd changes for 3.8 from the for-3.8 branch at

  git:// for-3.8

Included this time:

  - more nfsd containerization work from Stanislav Kinsbursky: we're not
    quite there yet, but should be by 3.9.

  - NFSv4.1 progress: implementation of basic backchannel security
    negotiation and the mandatory BACKCHANNEL_CTL operation.  See

    for remaining TODO's

  - Fixes for some bugs that could be triggered by unusual compounds.
    Our xdr code wasn't designed with v4 compounds in mind, and it
    shows.  A more thorough rewrite is still a todo.

  - If you've ever seen "RPC: multiple fragments per record not
    supported" logged while using some sort of odd userland NFS client,
    that should now be fixed.

  - Further work from Jeff Layton on our mechanism for storing
    information about NFSv4 clients across reboots.

  - Further work from Bryan Schumaker on his fault-injection mechanism
    (which allows us to discard selective NFSv4 state, to excercise
    rarely-taken recovery code paths in the client.)

  - The usual mix of miscellaneous bugs and cleanup.

Thanks to everyone who tested or contributed this cycle.
