From 5ff54dedf35bfee7a16eb9f8fb7ecadf7d5564cb Mon Sep 17 00:00:00 2001 From: Feng Zhou Date: Thu, 20 Apr 2023 11:27:35 +0800 Subject: selftests/bpf: Add test to access integer type of variable array Add prog test for accessing integer type of variable array in tracing program. In addition, hook load_balance function to access sd->span[0], only to confirm whether the load is successful. Because there is no direct way to trigger load_balance call.
