Subject: linux-next: manual merge of the device-mapper tree with the block
 tree

Hi all,

Today's linux-next merge of the device-mapper tree got a conflict in:

  include/linux/bio.h

between commit:

  57c47b42f454 ("block: turn bio_kmalloc into a simple kmalloc wrapper")

from the block tree and commit:

  135eaaabd22a ("block: allow using the per-cpu bio cache from bio_alloc_bioset")

from the device-mapper tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Cheers,
Stephen Rothwell
