       I got the error message listed below when I called read operation to
an opened rtdm file handle in main function.
       I have implemented the rt read operation in my rtdm driver allready.
       I think the main thread is allready turned into xenomai thread
because I have called rt_shadow_task function before the reading opreation.
       I wonder why this error message occurs.

       Error message from kernel.
       [155453.637967] [Xenomai] task at 1[42395][42395] called regular read()
on /dev/rtdm/fake_dev.
       Look forward to hearing from you.
      Thanks a lot.
