Subject: [PATCH] Add support for NVMe devices
Recognize NVMe Devices, so "parted -s /dev/nvme0n1" now prints
"NVMe Device (nvme)" instead of "Model: Unknown (unknown)".
In order for a device to be recognized as NVMe, it has to
have a 'blkext' major number. But since this major can be
used also by other device types, we also check the device
path contains 'nvme' as a substring.
* NEWS: Mention the change
* include/parted/device.h.in(PedDeviceType): Add PED_DEVICE_NVME
* libparted/arch/linux.c(BLKEXT_MAJOR): New define.
* libparted/arch/linux.c(_is_blkext_major): New function.
* libparted/arch/linux.c(_device_probe_type): Recognize NVMe devices.
* libparted/arch/linux.c(linux_new): Handle NVMe devices.
* parted/parted.c(do_print): Add "nvme" to list of transports.
