I'd be interested to hear Eduard's comment on that.
That said, I'll try to find some time to test "perf kmem" and provide feedback on that. I can ACK the patch when I'm happy with the output. :-)
I'm mostly interested in two scenarios: (1) getting a nice report on worst fragmented call-sites (perf kmem needs symbol lookup) and (2) doing "perf kmem record" on machine A (think embedded here) and then "perf kmem report" on machine B. I haven't tried kmemtrace-user for a while but it did support both of them quite nicely at some point.
Pekka
