This is a patch series that adds the event probe feature and tries to incorporate all of Masami's comments. While updating Tzvetomir's patch, I found some other things that could be changed as well, and some was added as extra patches. For instance, removing the customize struct size macros from kprobe and uprobe events and using the struct_size() macro. To implement "REC->type" and show the event type for the trace event, the traceprobe_set_print_fmt() needed to be updated to allow for that. Instead of allocating a temp buffer that traceprobe_parse_probe_arg() can manipulate, just have that function do the allocation instead of placing the burden onto the callers. Anyway, here's version 6! -- Steve Steven Rostedt (VMware) (6): tracing: Add DYNAMIC flag for dynamic events tracing: Have dynamic events have a ref counter tracing/probe: Have traceprobe_parse_probe_arg() take a const arg tracing/probes: Allow for dot delimiter as well as slash for system names tracing/probes: Use struct_size() instead of defining custom macros tracing/probe: Change traceprobe_set_print_fmt() to take a type Tzvetomir Stoyanov (VMware) (1): tracing: Add a probe that attaches to trace events ---- include/linux/trace_events.h | 52 ++- kernel/trace/Makefile | 1 + kernel/trace/trace.c | 4 +- kernel/trace/trace.h | 18 + kernel/trace/trace_dynevent.c | 38 ++ kernel/trace/trace_dynevent.h | 4 +- kernel/trace/trace_eprobe.c | 895 ++++++++++++++++++++++++++++++++++++ kernel/trace/trace_event_perf.c | 6 +- kernel/trace/trace_events.c | 22 +- kernel/trace/trace_events_synth.c | 21 +- kernel/trace/trace_events_trigger.c | 20 +- kernel/trace/trace_kprobe.c | 43 +- kernel/trace/trace_probe.c | 81 ++-- kernel/trace/trace_probe.h | 15 +- kernel/trace/trace_probe_tmpl.h | 6 +- kernel/trace/trace_uprobe.c | 34 +- 16 files changed, 1156 insertions(+), 104 deletions(-) create mode 100644 kernel/trace/trace_eprobe.c
