This is patch #3, and actual changes are in patch #6, I can change it to:
A follow-up patch "bpf: verify callbacks as if they are called
unknown number of times" changes logic for callbacks handling.
While previously callbacks were verified as a single function
call, new scheme takes into account that callbacks could be
executed unknown number of times.
...
Would that work?
