Linus once famously said "given enough eyeballs, all bugs are shallow".
There are already two block-over-RDMA driver pairs upstream (NVMeOF and
SRP). Accepting the IBTRS and IBNBD drivers upstream would reduce the
number of users of the upstream block-over-RDMA drivers and hence would
fragment the block-over-RDMA driver user base further. Additionally, I'm
not yet convinced that the interesting parts of IBNBD cannot be
integrated into the existing upstream drivers. So it's not clear to me
whether taking the IBTRS and IBNBD drivers upstream would help the Linux
user community.

Bart.
