    Unknown symbol nvme_find_pdev_from_bdev


      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
