Here is the start of the DM changes I've queued for 4.2 (via linux-dm.git's for-next branch). I'm posting them to the lists mainly to get feedback on the block changes (first 4 patches) and to publish Joe's dm-thinp discard improvements which depend on the new blkdev_issue_discard_async interface. Jens, if all looks OK please pick up the first 4 block patches. The "block: remove management of bi_remaining when restoring original bi_end_io" has been tested in terms of DM. I haven't tested btrfs, bcache, etc. All review/feedback is welcome. Thanks! Mike Christoph Hellwig (1): block, dm: don't copy bios for request clones Joe Thornber (5): block: factor out blkdev_issue_discard_async dm btree: add dm_btree_remove_leaves() dm thin metadata: add dm_thin_find_mapped_range() dm thin metadata: add dm_thin_remove_range() dm thin: range discard support Mike Snitzer (8): block: remove management of bi_remaining when restoring original bi_end_io block: remove export for blk_queue_bio dm: do not allocate any mempools for blk-mq request-based DM dm: rename methods that requeue requests dm: factor out a common cleanup_mapped_device() dm thin: cleanup overwrite's endio restore to be centralized dm thin: cleanup schedule_zero() to read more logically dm thin metadata: remove in-core 'read_only' flag block/bio-integrity.c | 4 +- block/bio.c | 20 -- block/blk-core.c | 99 +----- block/blk-lib.c | 57 ++- drivers/md/bcache/io.c | 2 +- drivers/md/dm-cache-target.c | 6 - drivers/md/dm-raid1.c | 2 - drivers/md/dm-snap.c | 1 - drivers/md/dm-table.c | 29 +- drivers/md/dm-thin-metadata.c | 117 +++++- drivers/md/dm-thin-metadata.h | 11 + drivers/md/dm-thin.c | 493 +++++++++++++++++--------- drivers/md/dm-verity.c | 2 +- drivers/md/dm.c | 314 +++++++--------- drivers/md/dm.h | 5 +- drivers/md/persistent-data/dm-block-manager.c | 6 + drivers/md/persistent-data/dm-block-manager.h | 1 + drivers/md/persistent-data/dm-btree-remove.c | 127 +++++++ drivers/md/persistent-data/dm-btree.h | 9 + fs/btrfs/disk-io.c | 2 +- fs/btrfs/volumes.c | 16 +- fs/btrfs/volumes.h | 2 - include/linux/bio.h | 1 - include/linux/blk_types.h | 3 + include/linux/blkdev.h | 11 +- 25 files changed, 806 insertions(+), 534 deletions(-) -- 2.3.2 (Apple Git-55) -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
