Subject: linux-next: build failure after merge of the block tree

Hi all,

After merging the block tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

block/bio.c: In function 'bio_add_zone_append_page':
block/bio.c:860:31: error: 'struct bio' has no member named 'bi_disk'
  860 |  struct request_queue *q = bio->bi_disk->queue;
      |                               ^~

Caused by commit

  309dca309fc3 ("block: store a block_device pointer in struct bio")

interacting with commit

  9f678097f3de ("block: add bio_add_zone_append_page")

from the btrfs tree.

I applied the following merge fix up for today.
