From: Yu Kuai <yukuai3@xxxxxxxxxx> Patch 1 add some bdev apis, then follow up patches will use these apis to avoid access bd_inode directly, and hopefully the field bd_inode can be removed eventually(after figure out a way for fs/buffer.c). Yu Kuai (14): block: add some bdev apis xen/blkback: use bdev api in xen_update_blkif_status() bcache: use bdev api in read_super() mtd: block2mtd: use bdev apis s390/dasd: use bdev api in dasd_format() scsicam: use bdev api in scsi_bios_ptable() bcachefs: remove dead function bdev_sectors() btrfs: use bdev apis cramfs: use bdev apis in cramfs_blkdev_read() erofs: use bdev api ext4: use bdev apis jbd2: use bdev apis gfs2: use bdev api nilfs2: use bdev api in nilfs_attach_log_writer() block/bdev.c | 116 +++++++++++++++++++++++++++++ block/bio.c | 1 + block/blk.h | 2 - drivers/block/xen-blkback/xenbus.c | 3 +- drivers/md/bcache/super.c | 11 ++- drivers/mtd/devices/block2mtd.c | 80 +++++++++----------- drivers/s390/block/dasd_ioctl.c | 5 +- drivers/scsi/scsicam.c | 3 +- fs/bcachefs/util.h | 5 -- fs/btrfs/disk-io.c | 68 ++++++++--------- fs/btrfs/volumes.c | 17 ++--- fs/btrfs/zoned.c | 12 ++- fs/cramfs/inode.c | 35 +++------ fs/erofs/data.c | 17 +++-- fs/erofs/internal.h | 1 + fs/ext4/dir.c | 6 +- fs/ext4/ext4_jbd2.c | 6 +- fs/ext4/super.c | 27 +------ fs/gfs2/glock.c | 2 +- fs/gfs2/ops_fstype.c | 2 +- fs/jbd2/journal.c | 3 +- fs/jbd2/recovery.c | 6 +- fs/nilfs2/segment.c | 2 +- include/linux/blkdev.h | 27 +++++++ include/linux/buffer_head.h | 5 +- 25 files changed, 273 insertions(+), 189 deletions(-) -- 2.39.2
