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

Hi all,

After merging the device-mapper tree, today's linux-next build (x86_64
allmodconfig) failed like this:

drivers/md/dm-zoned-target.c: In function 'dmz_ctr':
drivers/md/dm-zoned-target.c:779:17: error: implicit declaration of function 'bioset_create_nobvec' [-Werror=implicit-function-declaration]
  dmz->bio_set = bioset_create_nobvec(DMZ_MIN_BIOS, 0);
                 ^
drivers/md/dm-zoned-target.c:779:15: warning: assignment makes pointer from integer without a cast [-Wint-conversion]
  dmz->bio_set = bioset_create_nobvec(DMZ_MIN_BIOS, 0);
               ^

Caused by commit

  1e6562930ed7 ("dm zoned: drive-managed zoned block device target")

interacting with commit

  011067b05668 ("blk: replace bioset_create_nobvec() with a flags arg to bioset_create()")

from the block tree.

I have applied this merge fix patch for today:
