Why did I receive the following error message when passing the example
line "add fe4d7c9d-b8c6-4a70-9ef1-3d8a58d18eed A=1 B=abc" using the
original mainline code?

synth uevent: /devices/virtual/block/ram12: incorrect uevent action arguments
block ram12: uevent: failed to send synthetic uevent: -22

Is there a problem with my test case, or is the original code unable
to successfully parse the sample?
