From 2dfb40121ee83139909e4e17d414eee87897bb8e Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 25 Jan 2019 15:24:42 -0800 Subject: [PATCH] selftests: bpf: prepare for break up of verifier tests test_verifier.c has grown to be very long (almost 16 kLoC), and it is very conflict prone since we always add tests at the end. Try to break it apart a little bit. Allow test snippets to be defined in separate files and include them automatically into the huge test array.
