Upstream patch to support partitions for bcache

Partition support of bcache is from Linux kernel v4.10, which is newer than
kernel from Leap 42.1 and 42.2. We have request from community to add a patch
to support partition which is very useful to Ceph.

Here I quote the message from requester,
" this partitions support patch for bcache would significantly help
us when using bcache to speed up access to complete HDDs, i.e. as
a base device for Ceph OSDs.
May I ask you to backport below patch into the openSUSE mainline
kernels, for Leap 42.1 and 42.2? I'd be straight-forward and we'd
really appreciate this. (Looking even at
kernel-source-4.4.36-8.1.noarch, this patch is not included. And
our production Ceph nodes are still on Leap 42.1 - we'll start
migrating to 42.2 not before April)."

The procedure of openSUSE Fate is heavy for this fix (a patch for 5 lines
change), so I add a bugzilla entry to trace this change into Leap 42.1 and 42.2
kernel.
