/*! @file
* @brief Check how rtems_bdbuf_sync() works.
*
* Test sequence:
* -# Call rtems_bdbuf_read(#N) in thread #1.
* -# Call rtems_bdbuf_sync(#N) in thread #1.
* -# After a while disk driver gets write request for block #N.
* Notify bdbuf about write complete event.
* -# Check that rtems_bdbuf_sync(#N) in thread #1 unlocked after this.
* -# Call rtems_bdbuf_read(#N) in thread #2.
* -# Check that buffer is successfully obtained in thread #2.
* -# Call rtems_bdbuf_release(#N) in thread #2.
* .
