Hi,

Currently it is not possible to create partitions on bcache devices,
eg, if you have bcache0 you can't create bcache0p1, bcache0p2, etc.

There are patches [0] out there which 'enable' this, but they aren't
suited to be send upstream.

For the Ceph [1] project it would be very beneficial if bcache would
support the creation of partitions on the devices.
What's the use case exactly? You can create LVM lvs on bcache devices
if you need to split them. And I don't really understand why it would
be beneficial to Ceph, which is about agreggating many devices.
