Yeah I wanted to suppress extraneous output from everybody, I just happened to
notice it because I was testing net. The default thing already spits out what
it's running and pass/fail, there's no need to include all of the random output
unless the user wants to go and run the test manually. As it is now it's
_impossible_ to tell what ran and what passed/failed because of all the random
output.

Ideally kselftests would work like xfstests does and simply capture the output
to a log so you could go check afterwards, but that's a lot more work. Making
it easier to tell which tests passed/failed is a good enough first step.
Thanks,

Josef
