Epic Name:Test perf in LKFT
Guenter Roeck requested that we add some simple perf tests, due to a recent regression.
It will be sufficient to verify basic perf functionality.
Here are the regressions details from Guenter:
See upstream commit 528871b4560 ("perf/core: Fix impossible ring-buffer
sizes warning"); that should explain it. In a nutshell, even simple
perf commands didn't work anymore. Unfortunately, the commit breaking
it (upstream 9dff0aa95a32) propagated at least into v4.19.y and v4.14.y
by the time the problem was discovered.
