Making it easier to disable perf entirely would be desirable for one use case.
I can't do a trinity run for more than a few hours for the last few months
without hitting perf/ftrace bugs that no-one seems to be able to get their
heads around.
It would be useful if I could in the meantime find bugs in other parts of the
kernel by disabling all the affected code.
