PS2, Line 28: kretprobe:ksys_write / comm == str($1) && @start[tid] /
I've removed the additional `comm == str($1)` for `kretprobe`.
We may actually need this "comm == str($1) && ", not because is really needed, but because bpftrace in debian13 is buggy and otherwise it throws an error with an error trying to access a non-existing entry in the "start" map for "tid".
This works fine on older (debian12) and newer (archlinux) bpftrace.
