I'd advocate to discuss this at LSF.
Now that Mike moved the bio-based mpath stuff back in things got even
more complex.

I'll be posting a patchset for reimplementing multipath as a stand-alone
driver shortly; that'll give us a good starting point on how we want
multipath to evolve.

Who knows; we might even manage to move multipath out of device-mapper
altogether.
That would make Mike very happy, and I wouldn't mind, either :-)

Cheers,

Hannes
