Subject: [PATCH v4 3/8] perf tests: Avoid fork in perf_has_symbol test
Date: Tue, 13 Feb 2024 20:53:51 -0800 [thread overview]
Message-ID: <20240214045356.748330-4-irogers@google.com> (raw)
In-Reply-To: <20240214045356.748330-1-irogers@google.com>
perf test -vv Symbols is used to indentify symbols within the perf
binary. Add the -F flag so that the test command doesn't fork the test
before running. This removes a little overhead.
