    Unknown symbol nvme_find_pdev_from_bdev

    dfedorov.ciena

      Hi all,

       

      After installing MLNX_OFED_LINUX-4.4-1 on Ubuntu 18.04 (kernel 4.15.0-24) as "$ mlnxofedinstall --force --without-dkms --with-nvmf" I'm trying to use RDMA tools, but

       

      - modprobe on nvme_rdma fails with "nvme_rdma: Unknown symbol nvme_delete_wq (err 0)"

      - modprobe on nvmet_rdma fails with "nvmet: Unknown symbol nvme_find_pdev_from_bdev (err 0)"

       

      What am I doing wrong, please?

       

      I see two kernel modules loaded: nvme and nvme_core.

       

      This is Mellanox MCX516A-CCAT ConnectX-5 EN Network Interface Card 100GbE Dual-Port QSFP28.

       

      Any inputs will be greatly appreciated

       

      Thank you
