X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fe092fc9f14baca61d5f159cd00e2c9f9a60c2ef;p=users%2Fjedix%2Flinux-maple.git

selftests/seccomp: Flush benchmark output

When running the seccomp benchmark under a test runner, it wouldn't
provide any feedback on progress. Set stdout unbuffered.
