[PATCH 0/4] perf header: Save and reuse feature information in header (v4)

[Namhyung Kim]

Hi,

Currently the perf header information is used only at initial setup
time and discarded.  If it's saved we could reuse the information for
various purpose in the future.

Thanks,
Namhyung


v3 -> v4:
 * rename perf_header_info to perf_session_env (Arnaldo)

v2 -> v3:
 * patch 1-3 in v2 merged into tip
 * rebased on current acme/perf/core

v1 -> v2:
 * not touch EVENT_DESC feature handling
 * split out struct perf_header_info
 * simplify multi-string handling
 * add some cleanup patches

Namhyung Kim (4):
  perf header: Add struct perf_session_env
  perf header: Add ->process callbacks to most of features
  perf header: Use pre-processed session env when printing
  perf header: Remove unused @feat arg from ->process callback
