From 526f2ac9f6a1d668fddf925897b55341bef22644 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Tue, 20 Feb 2024 19:41:50 -0800 Subject: [PATCH] perf tests: Avoid fork in perf_has_symbol test 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.
