[$] Preparing for the realtime future

Unlike many of the previous gatherings of the Linux realtime developers, theirmicroconference at the virtual 2020 Linux PlumbersConference had a different feel about it. Instead of being about when and how to get thefeature into the mainline, the microconference had two sessions that looked at whathappens after the realtime patches are upstream. That has not quite happenedyet, but is likely for the 5.10 kernel, so the developers werelooking to the future of the stable realtime trees and, relatedly, plansfor continuous-integration (CI) testing for realtime kernels.
