I would rephrase:

"The tail_call_info variables in the frames of all other subprog
contains reference to the tail_call_info present in frame of
main function."

to:

"The tail_call_info field in the stack frame of subprogs contains
reference to the tail_call_info field in the stack frame of main
BPF program."
