Hi again :-)
	This testcase changes UUID of a block device and will never
restore it. Swapon error occurs when there are two "ffffffff-
ffff-ffff-ffff-ffffffffffff" UUID in the system, for example, run this
testcase to test a block device firstly and then, test a loop device.

Maybe you should restore the UUID of the block device in cleanup().

Thanks
