Thank you for the warning! I can see how that could happen with chrt. I can't work out how it could happen with just taskset. Are you saying to be careful when combining them? That would make sense to me. Also I can't figure out what pgrap is. Do you mean pgrep? I think you must mean something else, because I don't see what pgrep has to do with priority inversion. But it shares a manpage with pkill. . . . I don't do real-time work, but I've always been curious to know more about it. And priority inversion seems like an interesting and challenging problem.

Grepping processes doesn't have anything to do with priority inversions and locking your system. But grepping processes then setting them to realtime priority sched_fifo 99 or could wreck havok > I don't do real-time work, but I've always been curious to know more about it. And priority inversion seems like an interesting and challenging problem. It can be fun. It is kind of a separate world on its own. Interestingly most of the popular OS-es by default are tuned for throughput not low latency. So configuring and getting everything just right is an interesting challenge (sometimes involving applying kernel patches, although lately that might not be necessary as some have been mainlined).
