Subject: [PATCH v2 0/3] admin-guide: extend perf-security with resource
 control, data categories and privileged users


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;

Alexey Budankov (4):
  perf-security: document perf_events/Perf resource control
  perf-security: document collected perf_events/Perf data categories
  perf-security: elaborate on perf_events/Perf privileged users
  perf-security: wrap paragraphs on 72 columns
