11 The NVM Express driver is for solid state drives directly
12 connected to the PCI or PCI Express bus. If you know you
13 don't have one of these, it is safe to answer N.

15 To compile this driver as a module, choose M here: the
16 module will be called nvme.

22 This option enables support for multipath access to NVMe
23 subsystems. If this option is enabled only a single
24 /dev/nvmeXnY device will show up for each NVMe namespace,
25 even if it is accessible through multiple controllers.
