Subject[PATCH v2 0/7] perf timechart improvements
This patch series adds more features to the perf timechart command:
* -n option that adds possibility to limit number of tasks on SVG
* -T option that adds possibility to show only tasks related info
* -T and -P options now work with `perf timechart record` command to keep small
* -g option that adds possibility to record and add callchain to the SVG so
it's now possible to understand why some task went to sleep or what code
path woke it up
* add titles to the SVG blocks so it's possible to see how long task is

* fix errors pointed out by Namhyung Kim <>
