From 8be602dadb2febb5e4cb367bff1162205bcf9905 Mon Sep 17 00:00:00 2001 From: Jiri Olsa Date: Wed, 16 Nov 2022 11:02:28 +0100 Subject: [PATCH] selftests/bpf: Make test_bench_attach serial Alexei hit another rcu warnings because of this test. Making test_bench_attach serial so it does not disrupts other tests during parallel tests run. While this change is not the fix, it should be less likely to hit it with this test being executed serially.
