From 8cf868affdc459beee1a941df0cfaba1673740e3 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (Red Hat)" Date: Mon, 28 Nov 2016 13:03:21 -0500 Subject: tracing: Have the reg function allow to fail Some tracepoints have a registration function that gets enabled when the tracepoint is enabled. There may be cases that the registraction function must fail (for example, can't allocate enough memory). In this case, the tracepoint should also fail to register, otherwise the user would not know why the tracepoint is not working.
