You mean just have perf_trace_event_submit() call perf_tp_event()
directly?
I have no problem with that. Although I may make that into a separate
patch to keep this patch as a 'move' and the other patch as the change.
Looking at the history of perf_trace_buf_submit(), it use to be more
than one function call. But when you inlined
perf_swevent_put_recursion_context(), it became just a one2one mapping.
I'm assuming that we want to convert all calls to
perf_trace_buf_submit()s into perf_tp_event()?
