Some improvements for more clarity in the stack depth verification statistics output. See commit logs for details. Changelog: ---------- v3 -> v4 v3: https://lore.kernel.org/bpf/[email protected] * Read names from subprog_info directly to avoid an out-of-bounds access when func_info validation fails. (BPF CI Bot) v2 -> v3 v2: https://lore.kernel.org/bpf/[email protected] * Reuse subprog_name() to fetch subprogram names. (BPF CI Bot) v1 -> v2 v1: https://lore.kernel.org/bpf/[email protected] * Use multi-line format. (Eduard) * Adjust veristat to work with old and new format. * Adjust selftest log_level without new option.
