Subject: [PATCH 08/18] tracing: Indicate enabled soft-mode in enable file
Date: Fri, 10 May 2013 20:12:14 -0400 [thread overview]
Message-ID: <20130511001304.590286395@goodmis.org> (raw)
In-Reply-To: 20130511001206.477862307@goodmis.org
[-- Attachment #1: Type: text/plain, Size: 1213 bytes --]
From: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com>
Indicate enabled soft-mode event as "1*" in "enable" file
for each event, because it can be soft-disabled when disable_event
trigger is hit.
