  Modified files:
    sys/nfs              nfs_node.c 
  Log:
  Do not need (or want) to take a reference on an NFS file that
  is being deleted due to an forcible unmount. The problem is
  that vgone calls vclean() which then calls calls nfs_inactive()
  with VXLOCK set on the vnode. Nfs_inactive() was calling vget()
  to get a reference on the vnode, which in turn hung on VXLOCK.
  Nfs_inactive() now checks v_usecount to make sure that the vnode
  is not coming from vclean() before it does a vget().
