Subject: perf evsel: Remove symbol_conf usage
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=de446b40d5ddb2c3f1fe453ac405543663f9ac5d;p=linux-beck.git

perf evsel: Remove symbol_conf usage

  # perf test -v python
  16: Try 'import perf' in python, checking link problems      :
  --- start ---
  test child forked, pid 672
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
  ImportError: /tmp/build/perf/python/perf.so: undefined symbol:
  symbol_conf
  test child finished with -1
  ---- end ----
  Try 'import perf' in python, checking link problems: FAILED!
  #

To fix it just pass a parameter to perf_evsel__fprintf_sym telling if
callchains should be printed.
