Add the hist trigger testcases for ftracetest.
This checks the basic histogram trigger behaviors like as;
- Histogram trigger itself
- Histogram with string key
- Histogram with compound keys
- Histogram with sort key
- Histogram trigger modifiers (execname, hex, syscall)
- Multiple histograms on an event
- Named histogram
- Named histogram on multi events
Here is the test result.
