disposing fifo resources in fifo_cleanup() instead using of "vp->v_usecount == 1". There may be other references to the vnode, for instance by nullfs, at the time fifo_open() or fifo_close() is called, which could cause a resource leak. Don't bother grabbing the vnode interlock in fifo_cleanup() since it no longer accesses v_usecount. |
