[PATCH v3 00/10] libmpathpersist fixes and some more

[Martin Wilck <mwilck@suse.com>]

Hi Christophe,

this is v3 of my small set of libmpathpersist fixes. It's based
on your latest push. Sorry again for missing that.

Changes wrt v2:
 - rebased to latest upstream (39ad8dc8)
 - added another gcc 8.1 fix, and another small patch I hadn't
   submitted yet

Changes wrt v1:
 - introduce and use get_unaligned_be64 (Bart van Assche)
 - add test for (get|put)_unaligned_bexx functions

Note: we have both the "unaligned" and the "beXY_to_cpu" APIs
now, for essentially the same purpose. I wonder if we should
settle on a single API instead. I am unsure if beXY_to_cpu() has
alignment issues on some architectures (I don't think there are
issues on our current main target platforms). If yes, I believe that
we'd be on the safe side using the "unaligned" API.
Anyway, that could be done in a follow-up patch.

Thanks,
Martin
