Subject: [PATCH 05/11] tracing: Indicate enabled soft-mode in enable file
Date: Thu, 09 May 2013 14:44:26 +0900 [thread overview]
Message-ID: <20130509054426.30398.28202.stgit@mhiramat-M0-7522> (raw)
In-Reply-To: <20130509054405.30398.73831.stgit@mhiramat-M0-7522>
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.
