  Modified files:
    sys/kern             vfs_default.c 
  Log:
  Fix incorrect double-termination of vm_object.  When a vm_object is
  terminated and flushes pending dirty pages it is possible for the
  object to be ref'd (0->1) and then deref'd (1->0) during termination.
  We do not terminate the object a second time.
  
  Document vop_stdgetvobject() to explicitly allow it to be called without
  the vnode interlock held (for upcoming sync_msync() and ffs_sync()
  performance optimizations)
