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

Hi Jens,

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

fs/btrfs/inode.c: In function 'btrfs_endio_direct_read':
fs/btrfs/inode.c:8278:7: error: 'struct bio' has no member named 'bi_error'
    bio->bi_error = 0;
       ^

Caused by commit

  4e4cbee93d56 ("block: switch bios to blk_status_t")

interacting with commit

  674d8fe747c8 ("Btrfs: tolerate errors if we have retried successfully")

from the btrfs-kdave tree.

I appled that following merge fix patch:
