Subject: [PATCH 2/7] uprobes: Kill the "uprobe != NULL" check in uprobe_unregister()
Date: Fri, 23 Nov 2012 21:28:02 +0100 [thread overview]
Message-ID: <20121123202802.GA18884@redhat.com> (raw)
In-Reply-To: <20121123202741.GA18858@redhat.com>
Trivial. uprobe can't be NULL after mutex_unlock(), it was already used.
Signed-off-by: Oleg Nesterov <oleg@redhat.com>
