Message-ID: <20110322171251.GA4455@xanatos> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.20 (2009-06-14) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Has anyone successfully used the asynchronous I/O gadgetfs interface before? Specifically, has anyone used it for high-bandwidth isochronous traffic? I ask because I remember discovering about four years ago that there were several brain-twisty bugs in the in-kernel asynchronous I/O layer that gadgetfs uses. The AIO core also seemed to be largely unmaintained. Is this still true? Sarah Sharp
