Subject: [PATCH 15/15] uprobes: remove the unnecessary initialization in add_utask()
Date: Fri, 15 Jun 2012 17:44:01 +0200 [thread overview]
Message-ID: <20120615154401.GA9633@redhat.com> (raw)
In-Reply-To: <20120615154241.GA9524@redhat.com>
Trivial cleanup. No need to nullify ->active_uprobe after kzalloc().
