Message-ID: <20020130184950.GA22442@morgoth.mit.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.3.25i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I'm very much a newbie, and I'm wondering about the big kernel locks in tty_io.c. What exactly are the locks in the read and write for? Is the tty device that contested? Couldn't a finer grained lock be used? -Alex Khripin
