Date: Wed, 24 Oct 2007 22:17:19 +0530 From: "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> To: linux-ext4@...r.kernel.org Cc: "Aneesh Kumar K.V" <aneesh.kumar@...ux.vnet.ibm.com> Subject: [PATCH] ext4: Enable delalloc and mballoc by default. This ensure we test the latest features more easily. We need an option to clear delayed alloc feature. Add nodealloc option.
