Hi Emy,

I'm a bit confused by your question, are you trying to modify an
obsolete system call let's say you want to instrument old code, it
should be moderately staightforward with kprobe. Lttng can read the
kprobes after.

Lttng can read the probes like this
here's some more info on kprobes

Hope this helps.
