Subject: [PATCH v4 5/6] trace-cmd: Fix "trace-cmd reset" command to restore the default value of set_event_pid
Date: Mon, 11 Mar 2019 10:33:38 +0200 [thread overview]
Message-ID: <20190311083339.21581-6-tstoyanov@vmware.com> (raw)
In-Reply-To: <20190311083339.21581-1-tstoyanov@vmware.com>
The "trace-cmd reset" command should restore ftrace to its default state.
This patch sets "tracing/set_event_pid" to an empty string,
when the "trace-cmd reset" command is executed.
