From e3f6a42272e028c46695acc83fc7d7c42f2750ad Mon Sep 17 00:00:00 2001 From: Marco Elver Date: Fri, 8 Nov 2024 12:34:25 +0100 Subject: [PATCH] tracing: Remove pid in task_rename tracing output Remove pid in task_rename tracepoint output, since that tracepoint only deals with the current task, and is printed by default. This also saves some space in the entry and avoids wasted padding.
