Hi Jens, this series cleanups up the block layer API so that APIs consumed by file systems are (almost) only struct block_devic based, so that file systems don't have to poke into block layer internals like the request_queue. I also found a bunch of existing bugs related to partition offsets and discard so these are fixed while going along. Changes since v2: - fix an inverted check in btrfs - set max_discard_sectors to 0 in all places where the flag was previously cleared - fix a few sligtly incorrect collected Acks Changes since v1: - fix a bisection hazard - minor spelling fixes - reorder hunks between two patches to make the changes more obvious - reorder a patch to be earlier in the series to ease backporting Diffstat: arch/um/drivers/ubd_kern.c | 2 block/blk-core.c | 4 - block/blk-lib.c | 124 ++++++++++++++++++++--------------- block/blk-mq-debugfs.c | 2 block/blk-settings.c | 74 ++++++++++++++++++++ block/blk.h | 14 --- block/fops.c | 2 block/genhd.c | 4 - block/ioctl.c | 48 ++++++++++--- block/partitions/core.c | 12 --- drivers/block/drbd/drbd_main.c | 51 ++++++-------- drivers/block/drbd/drbd_nl.c | 94 +++++++++++--------------- drivers/block/drbd/drbd_receiver.c | 13 +-- drivers/block/loop.c | 15 +--- drivers/block/nbd.c | 5 - drivers/block/null_blk/main.c | 1 drivers/block/rbd.c | 1 drivers/block/rnbd/rnbd-clt.c | 6 - drivers/block/rnbd/rnbd-srv-dev.h | 8 -- drivers/block/rnbd/rnbd-srv.c | 5 - drivers/block/virtio_blk.c | 2 drivers/block/xen-blkback/blkback.c | 15 ++-- drivers/block/xen-blkback/xenbus.c | 9 -- drivers/block/xen-blkfront.c | 8 +- drivers/block/zram/zram_drv.c | 1 drivers/md/bcache/alloc.c | 2 drivers/md/bcache/request.c | 4 - drivers/md/bcache/super.c | 3 drivers/md/bcache/sysfs.c | 2 drivers/md/dm-cache-target.c | 9 -- drivers/md/dm-clone-target.c | 9 -- drivers/md/dm-io.c | 2 drivers/md/dm-log-writes.c | 3 drivers/md/dm-raid.c | 9 -- drivers/md/dm-table.c | 25 +------ drivers/md/dm-thin.c | 15 ---- drivers/md/dm.c | 3 drivers/md/md-linear.c | 11 --- drivers/md/md.c | 5 - drivers/md/raid0.c | 7 - drivers/md/raid1.c | 18 ----- drivers/md/raid10.c | 20 ----- drivers/md/raid5-cache.c | 8 +- drivers/md/raid5.c | 14 +-- drivers/mmc/core/queue.c | 3 drivers/mtd/mtd_blkdevs.c | 1 drivers/nvme/host/core.c | 4 - drivers/nvme/target/io-cmd-bdev.c | 2 drivers/nvme/target/zns.c | 3 drivers/s390/block/dasd_fba.c | 1 drivers/scsi/sd.c | 2 drivers/target/target_core_device.c | 20 ++--- drivers/target/target_core_file.c | 10 +- drivers/target/target_core_iblock.c | 17 +--- fs/btrfs/disk-io.c | 3 fs/btrfs/extent-tree.c | 8 +- fs/btrfs/ioctl.c | 12 +-- fs/btrfs/volumes.c | 4 - fs/btrfs/zoned.c | 3 fs/direct-io.c | 32 +-------- fs/exfat/file.c | 5 - fs/exfat/super.c | 10 -- fs/ext4/ioctl.c | 10 -- fs/ext4/mballoc.c | 10 +- fs/ext4/super.c | 10 -- fs/f2fs/f2fs.h | 3 fs/f2fs/file.c | 19 ++--- fs/f2fs/segment.c | 8 -- fs/fat/file.c | 5 - fs/fat/inode.c | 10 -- fs/gfs2/rgrp.c | 7 - fs/iomap/direct-io.c | 3 fs/jbd2/journal.c | 9 -- fs/jfs/ioctl.c | 5 - fs/jfs/super.c | 8 -- fs/nilfs2/ioctl.c | 6 - fs/nilfs2/sufile.c | 4 - fs/nilfs2/the_nilfs.c | 4 - fs/ntfs3/file.c | 6 - fs/ntfs3/super.c | 10 +- fs/ocfs2/ioctl.c | 5 - fs/super.c | 2 fs/xfs/xfs_discard.c | 8 +- fs/xfs/xfs_log_cil.c | 2 fs/xfs/xfs_super.c | 12 +-- fs/zonefs/super.c | 3 include/linux/blkdev.h | 112 +++++++++++-------------------- include/target/target_core_backend.h | 4 - mm/swapfile.c | 31 ++------ 89 files changed, 494 insertions(+), 651 deletions(-)
