Which bits? Why?
My current opinion is that you should:
Use md for raid1, raid5, raid6 - anything with redundancy. Use dm for multipath, crypto, linear, LVM, snapshot Use either for raid0 (I don't think dm has particular advantages for md or md over dm).
These can be mixed together quite effectively: You can have dm/lvm over md/raid1 over dm/multipath with no problems.
If there is functionality missing from any of these recommended components, then make a noise about it, preferably but not necessarily with code, and it will quite possibly be fixed.
