The merge is done. No change wrt your branch. Still not pushed to korg.
I struggle with a hwtable corruption with no /etc/multipath.conf ... can
you reproduce that ?

For example, iterating through the hwtable and printing ->product from
config.c:find_hwe() gives:

...
(StorEdge 3510|T4)
FC2502
RAIGE VOLUME
CSM200_R
LCSM100_[IEFS]
INF-01-00
FLEXLINE 380



hd

dcssblk

The final spurious entries are clearly from the blacklist mem region. I
verified the hwtable is not corrupted after initialization. Corruption
thus occurs between hwtable init and path discovery.

I'll continue tracking it, but if you see something obvious ...
