This test contains a set of 5 sub test cases which will tests the device add and replacement on a seed FS. The kernel messages are checked at the end of the each of the 5 test cases to see if there are any kernel warnings or bugs reported. As in general btrfs do report warning when device counts such as num_devices and rw_devices appears to be wrong.
Since the tests has to deal with the replace, it would need up to five scratch device with same size.
