Reduce the size of results folders with wltest
Created by: qperret
When using sched-evaluation-full-traced.yaml, the size of the result folder for 1 kernel can easily reach 25GB. With just 4 kernels, 100GB are needed. This is because the trace files are large, and contain a lot of trace events that are rarely necessary. It might be a good idea to collect less trace events in order to reduce the size of the results, and save some significant space when many kernels are tested.
