    nfs: Authentication performance improvements

    When file operations are sent to the NFS server, authorized filehandles
    are cached using the exportid, mountid, gfid and host as the key to the
    cache. This meant that any file OR directory will always fail on the
    *first* fop to that filehandle since the cache used the gfid as part of
    the key to the cache. However, if an export is authorized, this
    effectively means that ALL subdirectories and files in the export
    directory are authorized per the permissions of the export. This results
    slow times to walking a directory structure over an NFS mount.
