From 4c2b6f328742084a5bd770af7c3a2ef07828c41c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Philippe=20Mathieu-Daud=C3=A9?= Date: Thu, 6 Jun 2024 12:39:43 +0200 Subject: [PATCH] tracetool: Forbid newline character in event format MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Events aren't designed to be multi-lines. Multiple events can be used instead. Prevent that format using multi-lines by forbidding the newline character. Signed-off-by: Philippe Mathieu-Daudé Acked-by: Mads Ynddal Reviewed-by: Daniel P.
