Subject: [PATCH 03/18 v3] tracing: Add TRACE_SYSTEM_VAR to kvm-s390
Date: Thu, 02 Apr 2015 21:38:05 -0400	[thread overview]
Message-ID: <20150403014123.395140818@goodmis.org> (raw)
In-Reply-To: 20150403013802.220157513@goodmis.org

[-- Attachment #1: 0003-tracing-Add-TRACE_SYSTEM_VAR-to-kvm-s390.patch --]
[-- Type: text/plain, Size: 1312 bytes --]

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

New code will require TRACE_SYSTEM to be a valid C variable name,
but some tracepoints have TRACE_SYSTEM with '-' and not '_', so
it can not be used. Instead, add a TRACE_SYSTEM_VAR that can
give the tracing infrastructure a unique name for the trace system.
