Michael Lyle 62530ed8b1 bio: ensure __bio_clone_fast copies bi_partno ... A new field was introduced in 74d46992e0, bi_partno, instead of using bdev->bd_contains and encoding the partition information in the bi_bdev field. __bio_clone_fast was changed to copy the disk information, but not the partition information. At minimum, this regressed bcache and caused data corruption.
