Naming it 'nvme/ns<#>', kobject_set_name_vargs is going to change that
'/' into a '!', so the sysfs entry is named 'nvme!ns<#>'. Not a big
deal I suppose, but I just thought it looked odd since '!' has special
meaning in shells.
Otherwise, this is looking really solid, and test well on my single
ported NVMe. I had some trouble getting dual ported ones, but I've some
now and will run tests on those tomorrow with some failure injection.
