Subject: [PATCH 1/4] uprobes/powerpc: Don't clear TIF_UPROBE in do_notify_resume()
Date: Sun, 28 Oct 2012 18:39:25 +0100 [thread overview]
Message-ID: <20121028173925.GA14642@redhat.com> (raw)
In-Reply-To: <20121028173900.GA14621@redhat.com>
Cleanup. No need to clear TIF_UPROBE, do_notify_resume() does this.
