From bc7430cc8bfb51577e466a8ca02ad87375a70bde Mon Sep 17 00:00:00 2001 From: Andrii Nakryiko Date: Fri, 5 Jul 2019 08:50:11 -0700 Subject: selftests/bpf: convert selftests using BTF-defined maps to new syntax Convert all the existing selftests that are already using BTF-defined maps to use new syntax (with no static data initialization).
