Cover letter [PATCH V3 00/11] rtla improvements
This is a series of improvements for rtla, mainly as a result of our daily usage of the tool debugging problems at red hat.
The cgroup support and house keeping options are from our usage of the tool debugging containers.
The auto-analysis overhead reduction is needed when we go to large boxes - but it is really hand in practice, as it gives an idea of the problem without having to look at the trace.
Running hwnoise 100 % of CPU time might cause some systems to slow down too much. Reduce its utilization to 75% by default to avoid problems for people using it for the first time.
Finally, it adds support for running timerlat user-space threads, and to collect the additional field via rtla timerlat top/hist.
Changes from V2:
- Add timerlat hist -u option

Changes from V1:
- Add the user-space thread support to rtla timerlat top
