This patch replaces NVMe Open Channel API usage inside FTL library with corresponding zone bdev API calls. This include following calls: - spdk_nvme_ctrlr_cmd_get_log_page -> spdk_bdev_get_zone_info - spdk_nvme_ocssd_ns_cmd_vector_reset -> spdk_bdev_zone_management - spdk_nvme_ns_cmd_read -> spdk_bdev_read_blocks - spdk_nvme_ns_cmd_write_with_md -> spdk_bdev_write_blocks Change-Id: I1b5a6863d9ce72f4af1cfbb0e449fc1a5b638144 Signed-off-by: Wojciech Malikowski <wojciech.malikowski@intel.com> Reviewed-on: https://review.gerrithub.io/c/spdk/spdk/+/479702 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Community-CI: Broadcom SPDK FC-NVMe CI <spdk-ci.pdl@broadcom.com> Reviewed-by: Shuhei Matsumoto <shuhei.matsumoto.xt@hitachi.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Konrad Sztyber <konrad.sztyber@intel.com>
