From: Theodore Ts'o Subject: [PATCH, RFC] Clean up of delalloc code and map-on-close/rename fixes Date: Tue, 24 Feb 2009 00:05:46 -0500 Message-ID: <1235451952-2726-1-git-send-email-tytso@mit.edu> Cc: aneesh.kumar@linux.vnet.ibm.com To: linux-ext4@vger.kernel.org Return-path: Received: from thunk.org ([69.25.196.29]:40276 "EHLO thunker.thunk.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1751540AbZBXFGE (ORCPT ); Tue, 24 Feb 2009 00:06:04 -0500 Sender: linux-ext4-owner@vger.kernel.org List-ID: Ok, here are the patches I was talking about at our call today. They clean up the delalloc code, and then add an ioctl for forcing delayed allocation blocks to be allocated. The last two patches force delayed allocation blocks to be allocated on close if the file had been previously truncated, and on rename if the old file is displacing another file. I would appreicate some review. Thanks!! - Ted
