Subject: Re: [PATCH 00/26] tracing: 'hist' triggers

Hi Tom,

I've tested your series of the hist trigger v10 with
these testcases included in the couple of patches, which
tests following features.

     - traceon-traceoff trigger
     - enable/disable_event trigger
     - snapshot trigger
     - stacktrace trigger
     - trigger filters

     - 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.
  ----
  # ./ftracetest test.d/trigger/
  === Ftrace unit tests ===
  [1] event trigger - test event enable/disable trigger   [PASS]
  [2] event trigger - test trigger filter [PASS]
  [3] event trigger - test histogram modifiers    [PASS]
  [4] event trigger - test histogram trigger      [PASS]
  [5] event trigger - test multiple histogram triggers    [PASS]
  [6] event trigger - test snapshot-trigger       [PASS]
  [7] event trigger - test stacktrace-trigger     [PASS]
  [8] event trigger - test traceon/off trigger    [PASS]

So I'm OK for your hist trigger series.
If you would not mind, please include these patches and my tested-by 
in your series to prove your series is good :)
