Subject: [PATCH 15/20] debugfs: Fix mount directory of debugfs by default in events.txt
Date: Tue, 15 Sep 2009 12:12:51 -0700 [thread overview]
Message-ID: <1253041976-1111-15-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <20090915181247.GA32167@kroah.com>
From: GeunSik Lim <leemgs1@gmail.com>
We need common default directory of denbugfs for consistency.
(debugfs's default directory is /sys/kernel/debug/ by debugfs.)
