Pull NVMe changes from Christoph: "Here is the current batch of nvme updates for 4.18, we have a few more patches in the queue, but I'd like to get this pile into your tree and linux-next ASAP. The biggest item is support for file-backed namespaces in the NVMe target from Chaitanya, in addition to that we mostly small fixes from all the usual suspects." * 'nvme-4.18-2' of git://git.infradead.org/nvme: nvme: fixup memory leak in nvme_init_identify() nvme: fix KASAN warning when parsing host nqn nvmet-loop: use nr_phys_segments when map rq to sgl nvmet-fc: increase LS buffer count per fc port nvmet: add simple file backed ns support nvmet: remove duplicate NULL initialization for req->ns nvmet: make a few error messages more generic nvme-fabrics: allow duplicate connections to the discovery controller nvme-fabrics: centralize discovery controller defaults nvme-fabrics: remove unnecessary controller subnqn validation nvme-fc: remove setting DNR on exception conditions nvme-rdma: stop admin queue before freeing it nvme-pci: Fix AER reset handling nvme-pci: set nvmeq->cq_vector after alloc cq/sq nvme: host: core: fix precedence of ternary operator nvme: fix lockdep warning in nvme_mpath_clear_current_path
