Subject: [PATCH] udev/path_id: introduce support for NVMe devices (#4169)
This appends the nvme name and namespace identifier attribute the the
PCI path for by-path links. Symlinks like the following are now present:
lrwxrwxrwx. 1 root root 13 Sep 16 12:12 pci-0000:01:00.0-nvme-1 -> ../../nvme0n1
lrwxrwxrwx. 1 root root 15 Sep 16 12:12 pci-0000:01:00.0-nvme-1-part1 -> ../../nvme0n1p1
