From: Jiri Olsa Date: Wed, 16 Nov 2022 10:02:28 +0000 (+0100) Subject: selftests/bpf: Make test_bench_attach serial X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8be602dadb2febb5e4cb367bff1162205bcf9905;p=linux.git 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.
