I have sent Neil Brown an email asking for his thoughts on a possible code merge. Neil is on vacation until 10/7.
I would say that the EMVS MD code & original MD code are very similar. The most significant difference is the MD array discovery and setup code. EVMS MD does in-kernel discovery, whereas Linux MD has both in-kernel discovery (via fs/partitions/check.c) and user space initiated discovery (IOCTL).
