Subject: [PATCH v2 10/12] tracing: Remove orphaned trace_add/remove_event_call functions
Date: Mon,  5 Nov 2018 18:04:29 +0900
Message-ID: <154140866955.17322.2081425494660638846.stgit@devbox> (raw)
In-Reply-To: <154140838606.17322.15294184388075458777.stgit@devbox>

Remove trace_add_event_call() and trace_remove_event_call()
functions since those are not used anymore.
