Thanks Arnd, applied.

Actually I think we should replace the select with the depends. In
fact I though I had done that a while ago, but I must have messed it up.

Makes sense. I ran into the same problem on NVME_TARGET_RDMA now,
which otherwise needs dependencies on both CONFIG_BLOCK and

warning: (NVME_TARGET_LOOP && NVME_TARGET_RDMA) selects NVME_TARGET which has unmet direct dependencies (BLOCK && CONFIGFS_FS)

Folding in my patch below should address that too.

I folded this in.
