[PATCH RFC V2 0/5] partial callgrap and time support

[kan.liang@intel.com]

From: Kan Liang <kan.liang@intel.com>

This patchkit adds the ability to turn off callgraphs and time stamps
per event. This in term can reduce sampling overhead and the size of
the perf.data.

Changes since V1:
  - Break up V1 patches into three patches(parse option changes,
    partial time support and partial callgrap support).
  - Use strings 'fp,dwarf,lbr,no' to identify callchains
  - Add test case in parse-events.c

Kan Liang (5):
  perf,tools: introduce OPT_CALLBACK_SET/OPT_CALLBACK_NOOPT_SET
  perf/documentation: Add description for period
  perf,tool: partial time support
  perf,tool: partial callgrap support
  perf,tests: Add tests to callgrap and time parse
