I tested this series with my pm8001 v5 series on top. Everything looks
good, no problems detected with both SAS and SATA drives tests. So feel
free to add:

Martin,

This series and my pm8001 series have a conflict. When applying the
pm8001 patches on top of these libsas changes, patch 28 has a fairly
easy to resolve conflict. Let me know if you want me to send a v6
rebased on top of this.

Thanks !
