Re: [PATCH libdrm 1/4] tests: remove useless legacy tests

All of these 'tests' cover UMS functionality which is neither being worked on or actively maintained.

The only cases where developers touch UMS code is to unwrap it from the KMS codepaths and ensure that those are secure.

Anyone who feels strong about having these around can revive them, but in all honestly do consider _seriously_ what you're doing ;-)
