[PATCH bpf-next v4 0/3] Improve stack depth verification stats output

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

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/20260803031457.3115812-1-memxor@gmail.com

 * 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/20260802225209.2511758-1-memxor@gmail.com

 * Reuse subprog_name() to fetch subprogram names. (BPF CI Bot)

v1 -> v2
v1: https://lore.kernel.org/bpf/20260801230400.850271-1-memxor@gmail.com

 * Use multi-line format. (Eduard)
 * Adjust veristat to work with old and new format.
 * Adjust selftest log_level without new option. (Eduard)

Kumar Kartikeya Dwivedi (3):
  bpf: Show more useful info in stack depth stats
  selftests/bpf: Adjust veristat stack depth parsing
  selftests/bpf: Test stack depth stats without BTF subprog names
