I've just tested a mainline kernel version 4.17.0, and nvme names didn't float when using the kernel parameter "nvme_core.multipath=0", which reinforces that the fix patch is present in 4.17, so Guo: I guess your 4.17 version is really based on 4.17-rc1.
Let me know if there's anything else to investigate in this LP. In my understanding, we did have a bug after the nvme multipath introduction, but now kernel has a fix which is available upstream after kernel v4.17, and available in Ubuntu kernel 4.15.x series, after 4.15.0-34. To keep the nvme naming behavior as before, we need to use the kernel parameter "nvme_core.multipath=0".
