For the set:
Reviewed-by: Martin Wilck <mwilck@xxxxxxxx>

I have created a new branch 
https://github.com/openSUSE/multipath-tools/tree/upstream-tip

where this is series applied on my recently posted series
"libmultipath: improve cleanup on exit" (v3), in the hope that it will
pass review, too. It has to be this way around because your set
requires libmp_verbosity.

As soon as my series is finalized, this will be pushed to upstream-
queue.

Regards,
Martin
