  Log:
  Beat vnode locking in the NFS server code into submission.  This change
  is not pretty, but it fixes the code so that it no longer violates the
  vnode locking rules in the VFS API and doesn't trip any of the locking
  assertions enabled by the DEBUG_VFS_LOCKS kernel configuration option.
  There is one report that this patch fixed a "locking against myself"
  panic on an NFS server that was tripped by a diskless client.
