Hi Steve, Here are a few patches that should be applied on top of the 'Inter-event (e.g. latency) support v9' patchset. The first fixes another problem I noticed when printing flags. The rest implement the tracing/events/error_log suggested by Masami, and update the inter-event code to use it (and remove the old hist file error mechanism). Thanks, Tom The following changes since commit 404bb11b24fb9a592023c077b878d30ad6da4322: tracing: Enforce passing in filter=NULL to create_filter() (2018-04-11 11:18:42 -0400) are available in the git repository at: https://github.com/tzanussi/linux-trace-inter-event.git tzanussi/inter-event-update2 https://github.com/tzanussi/linux-trace-inter-event/tree/tzanussi/inter-event-update2 Tom Zanussi (6): tracing: Restore proper field flag printing when displaying triggers tracing: Add trace event error log tracing: Save the last hist command's associated event name tracing: Use trace event error_log with hist triggers tracing: Add field parsing trace event errors for hist triggers selftests: ftrace: Fix extended error support testcase kernel/trace/trace.h | 3 + kernel/trace/trace_events.c | 172 +++++++++++++++++++ kernel/trace/trace_events_hist.c | 188 +++++++++++---------- .../inter-event/trigger-extended-error-support.tc | 2 +- 4 files changed, 274 insertions(+), 91 deletions(-) -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
