Currently kernel kfunc bpf_dynptr_is_rdonly() has prototype: __bpf_kfunc bool bpf_dynptr_is_rdonly(struct bpf_dynptr_kern *ptr) while selftests bpf_kfuncs.h has extern int bpf_dynptr_is_rdonly(const struct bpf_dynptr *ptr) __ksym; Such a mismatch might cause problems although currently it is okay in selftests. Fix it to prevent future potential surprise.
