Subject: [PATCH bpf-next] selftests/bpf: make fexit_stress test run in serial mode
Date: Wed, 11 May 2022 16:20:12 -0700	[thread overview]
Message-ID: <20220511232012.609370-1-andrii@kernel.org> (raw)

fexit_stress is attaching maximum allowed amount of fexit programs to
bpf_fentry_test1 kernel function, which is used by a bunch of other
parallel tests, thus pretty frequently interfering with their execution.

Given the test assumes nothing else is attaching to bpf_fentry_test1,
mark it serial.
