2024-05-17selftests/bpf: Adjust test_access_variable_array after a kernel function ↵Martin KaFai Lau1-1/+1
name change After commit 4c3e509ea9f2 ("sched/balancing: Rename load_balance() => sched_balance_rq()"), the load_balance kernel function is renamed to sched_balance_rq. This patch adjusts the fentry program in test_access_variable_array.c to reflect this kernel function name change.

2023-04-19selftests/bpf: Add test to access integer type of variable arrayFeng Zhou1-0/+19
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.
