This allows more efficient block mapping including defined hole semantics, and is an important step toward getting rid of buffer_heads in XFS. Changes since V1: - added a conversion of ext2 to the iomap interface - addresse feedback from Ross, Dave and Robert From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Received: from bombadil.infradead.org ([198.137.202.9]:51648 "EHLO bombadil.infradead.org" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932545AbcINKBf (ORCPT ); Wed, 14 Sep 2016 06:01:35 -0400 From: Christoph Hellwig To: linux-xfs@vger.kernel.org, linux-fsdevel@vger.kernel.org, linux-nvdimm@ml01.01.org Cc: ross.zwisler@linux.intel.com Subject: iomap based DAX path V2 Date: Wed, 14 Sep 2016 12:01:19 +0200 Message-Id: <1473847291-18913-1-git-send-email-hch@lst.de> Sender: linux-fsdevel-owner@vger.kernel.org List-ID: This series adds a DAX I/O path based on the iomap interface.
