Many commits failed to build or boot during bisection.
At least the following four have to be reverted to make it work.
979c690d block: move clearing bd_invalidated into check_disk_size_change
f0b870d block: remove (__)blkdev_reread_part as an exported API
142fe8f block: fix bdev_disk_changed for non-partitioned devices
a1548b6 block: move rescan_partitions to fs/block_dev.c
