Subject: [PATCH] kobject: kzfree object in _release function
Date: Sun, 12 Apr 2009 00:16:26 +0800 [thread overview]
Message-ID: <1239466586-29410-1-git-send-email-tom.leiming@gmail.com> (raw)
From: Ming Lei <tom.leiming@gmail.com>
It helps to troubleshoot the __buggy__ case, in which
unreferenced objects are still accessed, using kzfree
to free objects safely in _release function.
