From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Hellwig Subject: [RFC] split struct kiocb Date: Tue, 27 Jan 2015 18:55:08 +0100 Message-ID: <1422381313-24034-1-git-send-email-hch@lst.de> Cc: Miklos Szeredi , linux-aio@kvack.org, linux-fsdevel@vger.kernel.org To: Al Viro Return-path: Received: from casper.infradead.org ([85.118.1.10]:39859 "EHLO casper.infradead.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751419AbbA0R4Z (ORCPT ); Tue, 27 Jan 2015 12:56:25 -0500 Sender: linux-fsdevel-owner@vger.kernel.org List-ID: This series cuts down the amount of fiels in the public iocb that is allocated on stack for every synchronous I/O, both by removing fields from it, and by adding a aio-specific iocb that is only allocated for aio requests. Additionally it cleans up various corner cases in the aio completion code and adds a simple in-kernel async read/write interface. Note that there still are some issues with fuse, see the first patch for details.
