From 98ce8e4a9dcfb448b30a2d7a16190f4a00382377 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Georg=20M=C3=BCller?= Date: Fri, 28 Jul 2023 17:18:12 +0200 Subject: [PATCH] perf test uprobe_from_different_cu: Skip if there is no gcc MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Without gcc, the test will fail. On cleanup, ignore probe removal errors. Otherwise, in case of an error adding the probe, the temporary directory is not removed.
