We actually recently added Python bindings to event tracing in perf: earth5:~/tip> find tools/perf/ -name '*.py' tools/perf/python/twatch.py tools/perf/util/setup.py tools/perf/scripts/python/Perf-Trace-Util/lib/Perf/Trace/Util.py tools/perf/scripts/python/Perf-Trace-Util/lib/Perf/Trace/Core.py tools/perf/scripts/python/Perf-Trace-Util/lib/Perf/Trace/SchedGui.py tools/perf/scripts/python/syscall-counts.py tools/perf/scripts/python/sctop.py tools/perf/scripts/python/sched-migration.py tools/perf/scripts/python/check-perf-trace.py tools/perf/scripts/python/futex-contention.py tools/perf/scripts/python/failed-syscalls-by-pid.py tools/perf/scripts/python/net_dropmonitor.py tools/perf/scripts/python/syscall-counts-by-pid.py tools/perf/scripts/python/netdev-times.py ... and Linus did not object (so far ;-) - nor does he IMHO have many reasons to object as long as the code is sane and useful. Nor did Linus object when perf extended its scope from profiling to tracing, system monitoring, etc. While i don't talk for Linus, the only 'hard boundary' that Linus enforces and expects all maintainers to enforce that i'm aware of is "don't do crazy crap". Everything else is possible as long as it's high quality and reasonable, with a good upside story that is relevant to the kernel - you can let your imagination run wild, there's no artificial barriers that i'm aware of. Anyway, i have outlined the rough consequences of a user-space project being inside the kernel repo in this post: http://lkml.org/lkml/2011/11/10/86 ... and they are definitely not trivial and easy to meet.
