From 906bd22a44c7c381ae92996129b075ea7beba8f6 Mon Sep 17 00:00:00 2001 From: Kumar Kartikeya Dwivedi Date: Wed, 5 Jul 2023 20:17:30 +0530 Subject: selftests/bpf: Add selftest for check_stack_max_depth bug Use the bpf_timer_set_callback helper to mark timer_cb as an async callback, and put a direct call to timer_cb in the main subprog. As the check_stack_max_depth happens after the do_check pass, the order does not matter. Without the previous fix, the test passes successfully.
