Hi, I think the purpose of NVME_QUIRK_BOGUS_NID is meant to fix the
problem that the id may vary per commit
00ff400e6deee00f7b15e200205b2708b63b8cf6 (“nvme: add a quirk to disable
namespace identifiers”). The id you have right now is the really fixed
one that it should have been. So I think ubuntu kernel should align with
the decision from the upstream here as well. I'm marking this as
WONTFIX.

Title:
Ubuntu 22.04 nvme WWID changed after upgrade kernel to 5.15.0-127
which occurred in specific nvme vendors
Status in linux package in Ubuntu:
Won't Fix
Bug description:
After updating kernel from 5.15.0-26 to 5.15.0-127, nvme disk WWID changed
from /dev/disk/by-id/nvme-eui.XXX to /dev/disk/by-id/nvme-nvme.XXX .
This issue happened on specific nvme vendor , such as Intel NVMe SSD :
8:00.0 Non-Volatile memory controller [0108]: Intel Corporation NVMe
Datacenter SSD [3DNAND, Beta Rock Controller] [8086:0a54]
After investigation, it was found that the introduction of
NVME_QUIRK_BOGUS_NID quirks has changed the device attribute file name format.
I submitted a patch to mainline to fix this problem, but this patch could not
be accepted because the implementation of the technology conflicted with the
policy of the decision maker.

Considering that naming formats need to have high stability and
recognizability on production,
For the Ubuntu kernel, which is widely used in enterprise environments,
changes to such underlying attribute can have a significant impact on
applications that rely on WWID. Especially in the case of minor kernel version
upgrade.
Is it possible remove NVME_QUIRK_BOGUS_NID flag?
