Subject: linux-next: manual merge of the block tree with Linus' tree

Hi Jens,

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

  drivers/md/dm-io.c

between commit:

  feb7695fe9fb ("dm io: fix duplicate bio completion due to missing ref count")

from Linus' tree and commit:

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

from the block 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
