Re: [PATCH 0/11] LTTng-core (basic tracing infrastructure) 0.5.108

Also, care to explain how kprobes can be used to access same data
without having to actually customize a probe point for every binary?

Thats why we have things like systemtap.

All we appear to lack is systemtap ability to parse debug data so it can
be told "trace on line 9 of sched.c and record rq and next"

But that's the whole point - if it's not integrated into a marker as
source code, it requires manual intervention for every bloody release
to do. "line 9 of sched.c" is a farcically stupid way of doing tags
on a dynamically moving project like the linux kernel.

Yes, that may work OK for something that is very static, like a distro
snapshot, but as a general mechanism, it's unsustainable and broken.
