What would that be? nvmf over RDMA suggest on-the-wire transport
encryption, which really is a different think that what fscrypt
and blk-crypto deal with.  NVMe has a Key per I/O TP, which is
still waiting for the messy TCG counter part, but as far as I
can tell it is in many ways designed to more or less intentionally
not fit the fscrypt model.
