[PATCH 0/2] tracing: Have bpf and perf reuse the tracefs TRACE_EVENT macros

[Steven Rostedt <rostedt@goodmis.org>]

When reviewing Linyu Yuan patches[1] where the change was to move most
the macros from perf and bpf into stages, I realized that the macros
that makes up perf and bpf events are duplicated from the tracefs
macros that were moved into the stages directory. One reason to move
them into that directory was to remove duplicate code.

Remove the macros that are duplicated in the bpf and perf code and use
stage 6, which is the macros used to build the data needed to record
the TRACE_EVENT() TP_fast_assign() into the trace. This will mean they
will pick up bug fixes, as well as any enhacements that are added.
