[PATCH 00/15] Candidates for 3.6 [v2]

[Chuck Lever <chuck.lever@xxxxxxxxxx>]

Hi-

Here is a second crack at the TEST_STATEID fixes and patches to
implement UCS.  I've attempted to address the following review
comments:

  o  The changes have been reorganized to allow the meaty parts of
     the TEST_STATEID fixes to be applied to -stable.

  o  Additional in-code comments have been introduced.

  o  FREE_STATEID is now performed in all cases after TEST_STATEID
     except when the TEST_STATEID operation result is
     NFS4ERR_BAD_STATEID.

  o  The change to check clp->cl_cons_state in
     nfs4_wait_clnt_recover() is now a separate patch with its own
     justification.

As before, there is one last bug to fix: rpcauth_create() returns
-EEXIST when replacing an RPC client's rpc_auth, if both the
existing and new rpc_auth are RPC_AUTH_GSS.  I should be able to
post a solution for review next week.

The final patch in this series is a hack, posted for discussion.
