Merge branch 'nvme-4.18-2' of git://git.infradead.org/nvme into for-4.18/block
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."
