	Backend-private context (private).

Detailed Description

Caller-allocated block-device handle binding a backend to its context.

Zero-initialise (= {}) and pass to a backend _init() helper, which fills the vtable and context. Treat the fields as private; reach the device only through the ra8_io_blockdev_* functions below. The handle and the backend's context must out-live every call made through them.

Invariant

iface is non-NULL once a backend has been bound.
