The patch set extends the first version of perf-security.rst documentation
file [1], [2], [3] with the following topics:

1) perf_events/Perf resource limits and control management that describes
RLIMIT_NOFILE and perf_event_mlock_kb settings for processes conducting
performance monitoring;

2) categories of system and performance data that can be captured by
perf_events/Perf with explicit designation of process sensitive data;

3) possible steps to create perf_event/Perf privileged users groups for
the current implementations of perf_events syscall API [4] and Perf tool;
