From f8186bf65ae6a4ce96d5cf52c2c9481c0e2193ce Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Wed, 30 Nov 2022 12:00:13 -0800 Subject: [PATCH] selftests/bpf: Make sure enum-less bpf_enable_stats() API works in C++ mode Just a simple test to make sure we don't introduce unwanted compiler warnings and API still supports passing enums as input argument.
