This is just a basic qemu boot test. No workload at all.

For logs, please see the next column of the qemu test results at
http://kerneltests.org/builders. You might have to dive into individual builds
if you check after a more recent -next kernel has been made available and your
changes were dropped in that kernel. Test results are available for about
a month.

Build and test scripts are available at https://github.com/groeck/linux-build-test.

Hope this helps,

Guenter
