Log:
  MFC: r244690
  Attempt to clarify that for ZFS, all file systems under
  the NFSv4 root must be exported. This is because ZFS
  checks exports itself.
  This is a content change.

 the entire tree that is rooted at that point must be in local file systems
 that are of types that can be NFS exported.
