Subject: perf stat: Do not indent headers for JSON
X-Git-Tag: v6.6.17~5897^2~154
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6d0a7e394eabd456f70c2f2f8e958b2343074360;p=platform%2Fkernel%2Flinux-rpi.git

perf stat: Do not indent headers for JSON

Currently --metric-only with --json indents header lines.  This is not
needed for JSON.

  $ perf stat -aA --metric-only -j true
        {"unit" : "GHz"}{"unit" : "insn per cycle"}{"unit" : "branch-misses of all branches"}
  {"cpu" : "0", {"metric-value" : "0.101"}{"metric-value" : "0.86"}{"metric-value" : "1.91"}
  {"cpu" : "1", {"metric-value" : "0.102"}{"metric-value" : "0.87"}{"metric-value" : "2.02"}
  {"cpu" : "2", {"metric-value" : "0.085"}{"metric-value" : "1.02"}{"metric-value" : "1.69"}
  ...

Note that the other lines are broken JSON, but it will be handled later.
