In my mind 'end of the call chain' means 'leaf function',
so the comment reads a bit misleading to me.
Here we're at the end of subprog.
It's not necessarily the leaf function.

Hmm you're right i'll try to rephrase that.

What about just:
"if tail call got detected across bpf2bpf calls then mark each of the
currently present subprog frames as tail call reachable subprogs"

sounds good to me.
