    NFSv4: Don't use the delegation->inode in nfs_mark_return_delegation()
    
    nfs_mark_return_delegation() is usually called without any locking, and
    so it is not safe to dereference delegation->inode. Since the inode is
    only used to discover the nfs_client anyway, it makes more sense to
    have the callers pass a valid pointer to the nfs_server as a parameter.

    nfs: don't use d_move in nfs_async_rename_done
    
    If the task that initiated the sillyrename ends up being killed by a
    fatal signal, then it will eventually return back to userspace and end
    up releasing the i_mutex. d_move however needs to be done while holding
    the i_mutex.
    
    Instead of using d_move here, just unhash the old and new dentries to
    prevent them from being found by lookups. With this change though, the
    dentries are now incorrect post-rename and do not reflect the actual
    name of the file on the server. I'm proceeding under the assumption
    that since they are unhashed that this isn't really a problem.
    
    In order for the sillydelete to still work though, the dname must be
    copied earlier when setting up the sillydelete info, and the name must
    be recopied if the sillydelete info has to be moved to a new dentry.

    NFS: Cleanup of the nfs_pageio code in preparation for a pnfs bugfix
    
    We need to ensure that the layouts are set up before we can decide to
    coalesce requests. To do so, we want to further split up the struct
    nfs_pageio_descriptor operations into an initialisation callback, a
    coalescing test callback, and a 'do i/o' callback.
    
    This patch cleans up the existing callback methods before adding the
    'initialisation' callback.

    NFS: test and free stateids during recovery
    
    When recovering open files and locks, the stateid should be tested
    against the server and freed if it is invalid.  This patch adds new
    recovery functions for NFS v4.1.

    NFS: added FREE_STATEID call
    
    FREE_STATEID is used to tell the server that we want to free a stateid
    that no longer has any locks associated with it.  This allows the client
    to reclaim locks without encountering edge conditions documented in
    section 8.4.3 of RFC 5661.

    NFS: Added TEST_STATEID call
    
    This patch adds in the xdr for doing a TEST_STATEID call with a single
    stateid. RFC 5661 allows multiple stateids to be tested in a single
    call, but only testing one keeps things simpler for now.

    NFS: Add SECINFO_NO_NAME procedure
    
    If the client is using NFS v4.1, then we can use SECINFO_NO_NAME to find
    the secflavor for the initial mount.  If the server doesn't support
    SECINFO_NO_NAME then I fall back on the "guess and check" method used
    for v4.0 mounts.

    can be skipped if the "eir_server_scope" from the exchange_id proc differs from
    previous calls.

    NFS: pnfs: loop over multipath addrs on connect
    
    Don't just use the first addr in the multipath list - instead, loop
    over addresses when calling nfs4_set_ds_client() (which calls connect)
    until it is successful.
    
    Although this is not real multipath support, it's a quick fix to handle when
    an MDS sends a list of addresses for a DS and some of the addr families are
    unsupported or misconfigured (like no routable ipv6 addr assigned).
    This will attempt all paths to the DS before giving up, instead of immediately
    falling back to the MDS.
    
    As before, an error encountered after a successful connect() will cause all
    i/o to fall back to the MDS.

    NFS: Parse and store all multipath DS addresses
    
    This parses and stores all addresses associated with each data server,
    laying the groundwork for supporting multipath to data servers.
    
     - Skips over addresses that cannot be parsed (ie IPv6 addrs if v6 is not
       enabled).  Only fails if none of the addresses are recognizable
     - Currently only uses the first address that parsed cleanly
     - Tested against pynfs server (modified to support multipath)

    Handle ipv6 remote addresses from GETDEVICEINFO
    
     - supports netid "tcp" for ipv4 and "tcp6" for ipv6 as rfc 5665 specifies
     - added ds_remotestr to avoid having to handle different AFs in every dprintk
     - tested against pynfs 4.1 server, submitting ipv6 support patch to pynfs
     - tested with IPv6 disabled, it compiles cleanly and relies on rpc_pton to
       refuse to accept IPv6 addresses
