Hi Shaohua,

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

drivers/md/raid1.c: In function 'raid1_write_request':
drivers/md/raid1.c:1359:7: error: 'struct bio' has no member named 'bi_error'
    bio->bi_error = -ETIMEDOUT;
       ^
drivers/md/raid5.c: In function 'raid5_make_request':
drivers/md/raid5.c:5712:8: error: 'struct bio' has no member named 'bi_error'
      bi->bi_error = -ETIMEDOUT;
        ^

Caused by commit

  261eb8c4c5a8 ("md: make suspend range wait timed out")

interacting with commit

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

from the block tree.

I applied the following merge fix patch:
