Latest SPDK stopped working on armv8 port for us.

When I checked in back to this commit it starts working.

    nvmf: make invalid rdma_req case into an assert



    The wr_id should never be NULL - it will always correspond to a request

    we previously posted.  Convert the check to an assert() so we notice if

    this ever happens (which would indicate a programming error somewhere

    else).



    While we're here, add a more robust check to make sure the request is

    actually in the correct array of requests for the connection being

    polled (also in an assert, since this should never fail in normal

    execution).

Hi,



Why do I get invalid user mode virtual address when I enabled DEBUG in
SPDK/DPDK ?



invalid usermode virtual address 0xffff8f600000

invalid usermode virtual address 0xffff0f800000

invalid usermode virtual address 0xffff0f400000



this is armv8.



Regards,

Oza.
