No need to apologize - you raised valid questions that have come up in the past and 
i am pretty good at ignoring early-in-the-morning aspect of mails ;-)

Great! :-)

If someone wants to dust off the 'trace' utility patches that are still in 
tip:tmp.perf/trace that would be fantastic. Thomas and Peter prototyped an 
ftrace-esque buffering model there, to have all events associated with a
single fd (and hence a single [per cpu] buffer).

Warning, they conflict left and right with the current code:

 kernel/sched.c
 kernel/trace/trace.c
 tools/perf/Makefile
 tools/perf/builtin-record.c
 tools/perf/util/event.c
 tools/perf/util/header.c
 tools/perf/util/parse-events.c
 tools/perf/util/session.c
 tools/perf/util/session.h

So it's quite a bit of work - and of course it was all very unfinished, not even 
reaching prototype stage really.

Thanks,

	Ingo
