Public bug reported:
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.
https://lore.kernel.org/all/20250308141102.34101-1-iece...@gmail.com/
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?
