I used the master branch, the code seems a little older,
It's true that the newer branches such as dm-4.10 have reused
kmultipathd.
Thanks,

Nack, you must be looking at older code. bio-based DM multipath makes
use of kmultipathd.
When suggesting changes please always make sure you're working with the
