[$] Storage testing

Ted Ts'o led a discussion on storage testing and, in particular, on his experience getting blktests running for his test environment, in a combined storage and filesystem session at the 2019 Linux Storage, Filesystem, and Memory-Management Summit. He has been adding more testing to his automated test platform, including blktests, and he would like to see more people running storage tests. The idea of his session was to see what could be done to help that cause.
