There's very little testing of dm-multipath for upstream work, as I've
seen tons of avoidable breakage.  Doesn't help that it uses a special
code path that one else uses.

Let's make this a little less personal.  Fact is that the SuSE trees
have tons of patches in there that never have even been sent upstream.
There's also tons that have been posted once or twice.  While I feel
your frustration with the SCSI process fully and we'll need to work on
that somehow, how about you do another round of dumping the DM patches
on the dm-devel list and Mike?

I'll ping some of the other worst offenders as time permits.
