Mike Snitzer's tested the dm stuff, I've tested it with bio integrity, the aoe driver, bcache and md. This paves the way for the dio rewrite, multipage bvecs, killing merge_bvec_fn, and more: The following changes since commit 342799dee522b11ec205dba7a5c7fe64f2a0fec0: bcache: Fix flushes in writeback mode (2013-10-10 21:13:20 -0700) are available in the git repository at: git://evilpiepirate.org/~kent/linux-bcache.git for-jens for you to fetch changes up to e5cb0350156d84c2c976bbc2435e66b2bbbf1edb: block: Don't save/copy bvec array anymore, share when cloning (2013-10-11 15:45:50 -0700) ---------------------------------------------------------------- Kent Overstreet (23): block: Use rw_copy_check_uvector() block: Consolidate duplicated bio_trim() implementations bcache: Kill unaligned bvec hack block: Abstract out bvec iterator dm: Use bvec_iter for dm_bio_record() block: Convert bio_iovec() to bvec_iter block: Convert bio_for_each_segment() to bvec_iter block: Immutable bio vecs block: Convert bio_copy_data() to bvec_iter bio-integrity: Convert to bvec_iter block: Kill bio_segments()/bi_vcnt usage block: Convert drivers to immutable biovecs aoe: Convert to immutable biovecs ceph: Convert to immutable biovecs block: Kill bio_iovec_idx(), __bio_iovec() rbd: Refactor bio cloning, don't clone biovecs dm: Refactor for new bio cloning/splitting block: Remove bi_idx hacks block: Generic bio chaining block: Rename bio_split() -> bio_pair_split() block: Introduce new bio_split() block: Kill bio_pair_split() block: Don't save/copy bvec array anymore, share when cloning Documentation/block/biodoc.txt | 7 +- arch/m68k/emu/nfblock.c | 13 +- arch/powerpc/sysdev/axonram.c | 21 +- block/blk-core.c | 36 +-- block/blk-flush.c | 2 +- block/blk-integrity.c | 40 +-- block/blk-lib.c | 12 +- block/blk-map.c | 6 +- block/blk-merge.c | 66 +++-- block/blk-throttle.c | 14 +- block/elevator.c | 2 +- block/scsi_ioctl.c | 39 +-- drivers/block/aoe/aoe.h | 10 +- drivers/block/aoe/aoecmd.c | 153 ++++------ drivers/block/brd.c | 16 +- drivers/block/drbd/drbd_actlog.c | 2 +- drivers/block/drbd/drbd_bitmap.c | 2 +- drivers/block/drbd/drbd_main.c | 27 +- drivers/block/drbd/drbd_receiver.c | 19 +- drivers/block/drbd/drbd_req.c | 6 +- drivers/block/drbd/drbd_req.h | 2 +- drivers/block/drbd/drbd_worker.c | 8 +- drivers/block/floppy.c | 16 +- drivers/block/loop.c | 27 +- drivers/block/mtip32xx/mtip32xx.c | 20 +- drivers/block/nbd.c | 14 +- drivers/block/nvme-core.c | 142 ++------- drivers/block/pktcdvd.c | 182 ++++++------ drivers/block/ps3disk.c | 7 +- drivers/block/ps3vram.c | 10 +- drivers/block/rbd.c | 89 +----- drivers/block/rsxx/dev.c | 6 +- drivers/block/rsxx/dma.c | 15 +- drivers/block/umem.c | 53 ++-- drivers/block/virtio_blk.c | 4 +- drivers/block/xen-blkback/blkback.c | 2 +- drivers/block/xen-blkfront.c | 55 +--- drivers/md/bcache/alloc.c | 4 +- drivers/md/bcache/bcache.h | 2 -
