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 [1] https://lore.kernel.org/lkml/cover.1585941485.git.zanussi@xxxxxxxxxx/ 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.
