Cover letter [RFC PATCH 0/2] Re-work CMB and add WDS support.
The first patch adds CMB into a generic pool, from there we'll allocate from the pool for the submission queues. In the future we can allocate SGLs and PRPs from the pool as well.
The second patch unfortunately bounces (memcpys) the data from host to CMB. I originally tried to map the CMB into userspace via a custom nvme mmap handler, but I'm dumb and could never get gup for direct io working correctly.
