+/*! @file
+ * @brief Check the behaviour of rtems_bdbuf_read() function 
+ * with different reports from disk device driver.
+ *
+ * Test sequence:
+ * -# Call rtems_bdbuf_read() function and return 0 from disk device 
+ *    driver ioctl() function, and the result of asynchronous read
+ *    complete notification is successful.
+ * -# Check that rtems_bdbuf_read() returns RTEMS_SUCCESSFUL and
+ *    provides buffer descriptor.
+ * -# Call rtems_bdbuf_read() function and return -1 from disk device
+ *    driver ioctl() function (there will be no asynchronous read 
+ *    complete notification).
+ * -# Check that rtems_bdbuf_read() returns RTEMS_IO_ERROR.
+ * -# Call rtems_bdbuf_read() function and return 0 from disk device
+ *    driver ioctl() function, but the result of asynchronous read 
+ *    complete notification is faulty (with some erroneous status).
+ * -# Check that rtems_bdbuf_read() returns that status and does not
+ *    return buffer descriptor.
