vn_closefile(fp,
    l)vn_closefile() simply calls
      vn_close(9) with the
      appropriate arguments.vn_fcntl(fp,
    com, data,
    l)vn_fcntl() simply locks the vnode and invokes the
      vnode operation
      VOP_FCNTL(9) with the
      command com and buffer data.
      The vnode is unlocked on return. If the operation is successful zero is
      returned, otherwise an appropriate error is returned.vn_ioctl(fp,
    com, data,
    l)vn_ioctl() simply locks the vnode and
      invokes the vnode operation
      VOP_IOCTL(9) with the
      command com and buffer data.
      The vnode is unlocked on return. If the operation is successful zero is
      returned, otherwise an appropriate error is returned.vn_read(fp,
    offset, uio,
    cred, flags)vn_poll(fp,
    events, l)vn_poll() simply calls
      VOP_POLL(9) with the
      events events and the calling lwp
      l. The function returns a bitmask of available
      events.vn_statfile(fp,
    sb, l)vn_statfile() basically calls the vnode operation
      VOP_GETATTR(9) and
      transfer the contents of a vattr structure into a struct stat. If the
      operation is successful zero is returned, otherwise an appropriate error
      code is returned.vn_write(fp,
