From 77606363094332415995db7e09ed532b8903fdb3 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Daniel=20P=2E=20Berrang=C3=A9?= Date: Wed, 23 Jan 2019 12:00:14 +0000 Subject: [PATCH] trace: enforce that every trace-events file has a final newline MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When generating the trace-events-all file, the build system simply concatenates all the individual trace-events files. If any one of those files does not have a final newline, the printf format string will have the contents of the first line of the next file appended to it, which is usually a '#' comment.
