  Modified files:
    sys/sys              vnode.h 
    sys/kern             vfs_subr.c 
  Log:
   - If vput() is called with a shared lock it must upgrade to an exclusive
     before it can call VOP_INACTIVE().  This must use the EXCLUPGRADE path
     because we may violate some lock order with another locked vnode if
     we drop and reacquire the lock.  If EXCLUPGRADE fails, we mark the
     vnode with VI_OWEINACT.  This case should be very rare.
   - Clear VI_OWEINACT in vinactive() and vbusy().
   - If VI_OWEINACT is set in vgone() do the VOP_INACTIVE call here as well.
