bio: ensure __bio_clone_fast copies bi_partno
A new field was introduced in 74d46992e0d9, 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. Signed-off-by: Michael Lyle <mlyle@lyle.org> Fixes: 74d46992e0d9 ("block: replace bi_bdev with a gendisk pointer and partitions index") Reported-by: Pavel Goran <via-bcache@pvgoran.name> Reported-by: Campbell Steven <casteven@gmail.com> Reviewed-by: Coly Li <colyli@suse.de> Reviewed-by: Ming Lei <ming.lei@redhat.com> Cc: <stable@vger.kernel.org> # 4.14 Signed-off-by: Jens Axboe <axboe@kernel.dk>
