Fixes for tracing subsystem
JIRA: https://issues.redhat.com/browse/RHEL-1491
This MR contains a few standalone fixes for the tracing subsystem up to 6.4. It's not meant to be exhaustive: fixes that triggered too many conflicts or required bringing in patches that add new functionality were not included.
