Cover letter [PATCH v2 0/2] tracing: Make synthetic events a separate option

Hi Steve,

These are the same patches as v1, but after posting v1 I realized that if you applied them on top of the other patchset I posted awhile back ("[PATCH 0/3] tracing: histogram internals doc, hist_debug, and misc") [1], you wouldn't be able to apply these.

So assuming you apply the other patchset first, these should apply cleanly on top of those.

Thanks,

Tom

v1 text:

Since synthetic events can now be used separately from hist triggers, it makes sense to actually separate them into different options. It also makes sense in terms of file bloat - trace_events_hist.c was getting very large and this makes it smaller and easier to follow.

Thanks,

Tom
