Well, 17a3585 ("pvscan: use alternate device names from DEVLINKS to
check filter") fixes a different issue. I had a remark about it in my
first post in this thread, but nobody has replied to that yet (hint:
I'd appreciate if someone did).
The "multipath_wwids_file" test makes most sense with an existing WWIDs
file and "multipath=off" boot parameter, or multipathd disabled in some
other way.
