From mboxrd@z Thu Jan 1 00:00:00 1970 From: Matthew Wilcox Subject: [PATCH v3 0/7] Page I/O Date: Sun, 13 Apr 2014 18:59:49 -0400 Message-ID: Cc: Matthew Wilcox , willy@linux.intel.com To: linux-fsdevel@vger.kernel.org, linux-mm@kvack.org, linux-kernel@vger.kernel.org, Andrew Morton Return-path: Sender: owner-linux-mm@kvack.org List-Id: linux-fsdevel.vger.kernel.org Hi Andrew, Now that 3.15-rc1 is out, could you queue these patches for 3.16 please? Patches 1-3 & 7 are, IMO, worthwhile cleanups / bug fixes, regardless of the rest of the patch set. If this patch series gets in, I'll take care of including the NVMe driver piece. It'll be a bit more tricky than the proof of concept that I've been flashing around because we have to make sure that the device responds better to page sized I/Os than accumulating larger I/Os. It's indisputably a win for brd and for other NVM technology devices that are accessed synchronously rather than through DMA. Matthew Wilcox (7): Remove block_write_full_page_endio() Factor clean_buffers() out of __mpage_writepage() Factor page_endio() out of mpage_end_io() Add bdev_read_page() and bdev_write_page() swap: Use bdev_read_page() / bdev_write_page() brd: Add support for rw_page brd: Return -ENOSPC rather than -ENOMEM on page allocation failure drivers/block/brd.c | 16 +++++++-- fs/block_dev.c | 63 ++++++++++++++++++++++++++++++++++ fs/buffer.c | 21 +++--------- fs/ext4/page-io.c | 2 +- fs/mpage.c | 84 +++++++++++++++++++++++---------------------- fs/ocfs2/file.c | 2 +- include/linux/blkdev.h | 4 +++ include/linux/buffer_head.h | 2 -- include/linux/pagemap.h | 2 ++ mm/filemap.c | 25 ++++++++++++++ mm/page_io.c | 23 +++++++++++-- 11 files changed, 178 insertions(+), 66 deletions(-) -- 1.9.1 -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
