[PATCH 0/4] Refactor data structures to support NFSv4 migration

[Chuck Lever <chuck.lever@oracle.com>]

Trond-

Here are four patches that move fields related to NFSv4 state from the
nfs_client struct to the nfs_server struct, in order to facilitate the
eventual implementation of NFSv4 migration.

This series should address all recent review comments.  It passes my
simple tests here:  Full cthon suite passes over NFSv4 against an
OpenSolaris 2009.6 NFS server, and a full -j3 kernel build on NFSv4
completes without hangs or lockdep splats on a two-way client.  The
kernel build usually generates some delegation activity with this
Solaris server.

      NFS: Move cl_state_owners and related fields to the nfs_server struct
      NFS: Allow walking nfs_client.cl_superblocks list outside client.c
