Series nvme: Allow for pre-defined UUID and subsystem NQN | expand

Commit Message

Shin'ichiro Kawasaki Nov. 8, 2023, 6:47 a.m. UTC 
From: Hannes Reinecke <hare@suse.de>

The UUID/wwid of a namespace might be assigned externally, so
we shouldn't register it in the 'out' files.
The current checks for UUID/wwid are just there to ensure that
if a UUID is present is should match the wwid setting.
So rather add a function _check_uuid() which does exactly that
and don't register the actual UUID in the 'out' files.

[Shin'ichiro: added check against def_subsys_uuid in _check_uuid()]
