[PATCH bpf-next v2 0/3] bpf: Maximum combined stack depth

[Paul Chaignon <paul.chaignon@gmail.com>]

This patchset dumps the maximum combined stack depth in verifier logs
and parses it in veristat.

Changes in v2:
  - Remove unnecessary max_stack_depth assignment (Eduard).
  - Fix and test incorrect handling of private stacks.
  - Add veristat metric (Eduard).

Paul Chaignon (3):
  bpf: Report maximum combined stack depth
  selftests/bpf: Test reported max stack depth
  veristat: Report max stack depth
