[PATCH v6 0/7] tracing: Creation of event probe

[Steven Rostedt <rostedt@goodmis.org>]

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!

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
