It's all part of the "linus.patch", which is most likely a recent -bk patch.

You might be able to patch a temporary 2.6.7 kernel with 2.6.7-udm1, and then 
copy over the contents of drivers/md/ to your non-mm tree. I don't *think* 
there are any affected files outside of drivers/md/ (maybe 
include/linux/device-mapper.h and dm-ioctl.h), but don't quote me on that. :)
