From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matthew Wilcox Subject: [PATCH v2 0/6] Miscellaneous DAX patches, take 2 Date: Fri, 3 Jul 2015 10:40:37 -0400 Message-ID: <1435934443-17090-1-git-send-email-matthew.r.wilcox@intel.com> Cc: Matthew Wilcox , willy@linux.intel.com To: linux-fsdevel@vger.kernel.org, linux-kernel@vger.kernel.org, Alexander Viro Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: linux-fsdevel.vger.kernel.org A miscellaneous set of patches to improve DAX. All are independent of each other. I dropped the DAX mmap support for block devices; I started trying to put in a sysfs toggle and ran into some difficulties, so just drop that part of the patch for now. There's no problem (that I know of) with the read()/write() portion of the patch. I fixed up the conflict between Dave Chinner's changes to ext4 and mine. I forgot the 'bdev_direct_access() may sleep' patch in the previous submission. Matthew Wilcox (6): dax: Add block size note to documentation dax: Use copy_from_iter_nocache ext4: Use ext4_get_block_write() for DAX vfs: Allow truncate, chomd and chown to be interrupted by fatal signals block: Add support for DAX reads/writes to block devices dax: bdev_direct_access() may sleep Documentation/filesystems/dax.txt | 6 ++++-- fs/block_dev.c | 10 ++++++++++ fs/dax.c | 8 +++++--- fs/ext4/file.c | 8 ++++---- fs/open.c | 9 ++++++--- 5 files changed, 29 insertions(+), 12 deletions(-) -- 2.1.4
