writeback: separate out include/linux/backing-dev-defs.h

2015-06-02T14:33:34+00:00

With the planned cgroup writeback support, backing-dev related declarations will be more widely used across block and cgroup; unfortunately, including backing-dev.h from include/linux/blkdev.h makes cyclic include dependency quite likely. This patch separates out backing-dev-defs.h which only has the essential definitions and updates blkdev.h to include it. c files which need access to more backing-dev details now include backing-dev.h directly. This takes backing-dev.h off the common include dependency chain making it a lot easier to use it across block and cgroup. v2: fs/fat build failure fixed.

NFSv4.1/pnfs: Separate out metadata and data consistency for pNFS

2015-03-27T16:39:38+00:00

The LAYOUTCOMMIT operation means different things to different layout types. For blocks and objects, it is both a data and metadata consistency operation. For files and flexfiles, it is only a metadata consistency operation. This patch separates out the 2 cases, allowing the files/flexfiles layout drivers to optimise away the data consistency calls to layoutcommit. Signed-off-by: Trond Myklebust

NFSv4.1/pnfs: Refactor pnfs_set_layoutcommit()

2015-03-27T16:39:36+00:00

pnfs_set_layoutcommit() and pnfs_commit_set_layoutcommit() are 100% identical except for the function arguments. Refactor to eliminate the difference. Signed-off-by: Trond Myklebust

pnfs: Refactor the *_layout_mark_request_commit to use pnfs_layout_mark_request_commit

2015-02-18T15:20:35+00:00

The File Layout's filelayout_mark_request_commit() is almost the Flex File Layout's ff_layout_mark_request_commit(). And that can be reduced by calling into nfs_request_add_commit_list(). Signed-off-by: Tom Haynes Signed-off-by: Trond Myklebust

Merge branch 'for-3.20/bdi' of git://git.kernel.dk/linux-block

2015-02-12T21:50:21+00:00

Pull backing device changes from Jens Axboe: "This contains a cleanup of how the backing device is handled, in preparation for a rework of the life time rules. In this part, the most important change is to split the unrelated nommu mmap flags from it, but also removing a backing_dev_info pointer from the address_space (and inode), and a cleanup of other various minor bits. Christoph did all the work here, I just fixed an oops with pages that have a swap backing. Arnd fixed a missing export, and Oleg killed the lustre backing_dev_info from staging. Last patch was from Al, unexporting parts that are now no longer needed outside" * 'for-3.20/bdi' of git://git.kernel.dk/linux-block: Make super_blocks and sb_lock static mtd: export new mtd_mmap_capabilities fs: make inode_to_bdi() handle NULL inode staging/lustre/llite: get rid of backing_dev_info fs: remove default_backing_dev_info fs: don't reassign dirty inodes to default_backing_dev_info nfs: don't call bdi_unregister ceph: remove call to bdi_unregister fs: remove mapping->backing_dev_info fs: export inode_to_bdi and use it in favor of mapping->backing_dev_info nilfs2: set up s_bdi like the generic mount_bdev code block_dev: get bdev inode bdi directly from the block device block_dev: only write bdev inode on close fs: introduce f_op->mmap_capabilities for nommu mmap support fs: kill BDI_CAP_SWAP_BACKED fs: deduplicate noop_backing_dev_info

pnfs: pass ds_commit_idx through the commit path

2015-02-03T19:06:45+00:00

Pass ds_commit_idx through the nfs commit path. It's used to select the commit bucket when using pnfs and is ignored when not using pnfs. Several functions had to be changed: nfs_retry_commit, nfs_mark_request_commit, pnfs_mark_request_commit and the pnfs layout driver .mark_request_commit functions. Signed-off-by: Tom Haynes

nfs: rename pgio header ds_idx to ds_commit_idx

'ds_commit_idx' is a better name - it is used to select the right commit bucket for pnfs. Signed-off-by: Weston Andros Adamson

pnfs: release lseg in pnfs_generic_pg_cleanup

This is needed to support mirrored writes - the first write can't just trash the lseg, we need to keep it around until all mirrors have written. Signed-off-by: Weston Andros Adamson
