  Log:
  MFC rev. 1.97:
  Lock the vnode around the call to VOP_GETATTR. Move the locked code
  and vn_fullpath (that call malloc(..., M_WAITOK)) from under the
  vm object lock, since sleep is not allowed while holding the mutex.
  
  Being there, wrap VOP_GETATTR call with conditional Giant aquire.
  Currently this is (almost) noop because pseudofs is Giant-locked.
