  SVN rev 210739 on 2010-08-01 23:36:39Z by rmacklem
  
  MFC: r210178
  Patch the experimental NFSv4 server so that it acquires a reference
  count on nfsv4rootfs_lock when dumping state, since these functions
  are not called by nfsd threads. Without this reference count, it
  is possible for an nfsd thread to acquire an exclusive lock on
  nfsv4rootfs_lock while the dump is in progress and then change the
  lists, potentially causing a crash.
