SubjectRe: [RFC][PATCH 1/2] perf: Add 'perf kmem' tool

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
