The RDMA support in GlusterFS is completely opaque to QEMU.
All we have there is the CLI syntax to enable use of the
RDMA support inside libglusterfs. I'm not convinced that
the justification for deprecation (lack of maintanier)
applies to this scenario.

I agree with Thomas that each functional area listed here
should be handld in a separate patch, since they're all
independant.
