Are you referring to any of this :-

1. Split nvmet_passthru_execute_cmd() into
    nvmet_passthru_execute_io_cmd() and
    nvmet_passthru_execute_admin_cmd() handler just like as bdev-ns and
    file-ns. (I don't think so that is what you mean).

OR

2. Split the nvme_alloc_request() into nvme_alloc_request_qid_any() and
    nvme_alloc_request_qid() then call nvme_alloc_request_qid_any() from
    passthru fast path ? (or variation of the same).

OR

Can you please elaborate how you like to have a split ?
