I wonder where this sort of idea comes from.... Obviously individual distributions are free to support or not support whatever bits of code they like. And developers are free to add duplicate functionality to the kernel (I believe someone is working on a raid5 target for dm). But that doesn't mean that anything is going to be 'phased out'. md and dm, while similar, are quite different. They can both comfortably co-exist even if they have similar functionality. What I expect will happen (in line with what normally happens in Linux) is that both will continue to evolve as long as there is interest and developer support. They will quite possibly borrow ideas from each other where that is relevant. Parts of one may lose support and eventually die (as md/multipath is on the way to doing) but there is no wholesale 'phasing out' going to happen in either direction.
