From a237dda05e9101404a634ac53ee65c8f8c8fce58 Mon Sep 17 00:00:00 2001 From: Anton Protopopov Date: Mon, 13 Feb 2023 09:15:18 +0000 Subject: [PATCH] selftest/bpf/benchs: Print less if the quiet option is set The bench utility will print Setting up benchmark ''... Benchmark '' started. on startup to stdout. Suppress this output if --quiet option if given. This makes it simpler to parse benchmark output by a script.
