Hi Jens, this series contains a bunch of different BDI cleanups. The biggest item is to isolate block drivers from the BDI in preparation of changing the lifetime of the block device BDI in a follow up series. Changes since v3: - rebased on the lasted block tree, which has some of the prep changes merged - extend the ->ra_pages changes to ->io_pages - move initializing ->ra_pages and ->io_pages for block devices to blk_register_queue Changes since v2: - fix a rw_page return value check - fix up various changelogs Changes since v1: - rebased to the for-5.9/block-merge branch - explicitly set the readahead to 0 for ubifs, vboxsf and mtd - split the zram block_device operations - let rw_page users fall back to bios in swap_readpage Diffstat: block/blk-core.c | 3 - block/blk-integrity.c | 4 +- block/blk-mq-debugfs.c | 1 block/blk-settings.c | 5 +- block/blk-sysfs.c | 4 +- block/genhd.c | 13 +++++-- drivers/block/aoe/aoeblk.c | 2 - drivers/block/brd.c | 1 drivers/block/drbd/drbd_nl.c | 18 --------- drivers/block/drbd/drbd_req.c | 4 -- drivers/block/rbd.c | 2 - drivers/block/zram/zram_drv.c | 19 +++++++--- drivers/md/bcache/super.c | 4 -- drivers/md/dm-table.c | 9 +--- drivers/md/raid0.c | 16 -------- drivers/md/raid10.c | 46 ++++++++---------------- drivers/md/raid5.c | 31 +++++++--------- drivers/mmc/core/queue.c | 3 - drivers/mtd/mtdcore.c | 2 + drivers/nvdimm/btt.c | 2 - drivers/nvdimm/pmem.c | 1 drivers/nvme/host/core.c | 3 - drivers/nvme/host/multipath.c | 10 +---- drivers/scsi/iscsi_tcp.c | 4 +- fs/9p/vfs_file.c | 2 - fs/9p/vfs_super.c | 6 ++- fs/afs/super.c | 1 fs/btrfs/disk-io.c | 2 - fs/fs-writeback.c | 7 ++- fs/fuse/inode.c | 4 +- fs/namei.c | 4 +- fs/nfs/super.c | 9 ---- fs/super.c | 2 + fs/ubifs/super.c | 2 + fs/vboxsf/super.c | 2 + include/linux/backing-dev.h | 78 +++++++----------------------------------- include/linux/blkdev.h | 3 + include/linux/drbd.h | 1 include/linux/fs.h | 2 - mm/backing-dev.c | 13 +++---- mm/filemap.c | 4 +- mm/memcontrol.c | 2 - mm/memory-failure.c | 2 - mm/migrate.c | 2 - mm/mmap.c | 2 - mm/page-writeback.c | 18 ++++----- mm/page_io.c | 18 +++++---- mm/swapfile.c | 4 +- 48 files changed, 144 insertions(+), 253 deletions(-)
