Subject: linux-next: manual merge of the scsi-mkp tree with the block tree

Hi all,

Today's linux-next merge of the scsi-mkp tree got conflicts in:

  block/blk-settings.c
  include/linux/blkdev.h

between commit:

  e4eb37cc0f3e ("block: Remove elevator required features")

from the block tree and commit:

  ec84ca4025c0 ("scsi: block: Remove now unused queue limits helpers")

from the scsi-mkp 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
