I see you already took the change; but regardless the idea of splitting
MD and DM files into separate directories was explored briefly (by me).
I stopped short of that because dm-raid.c does share code with md (see
all the md includes at the top of dm-raid.c).

Would require more extensive work to formalize the MD interfaces through
include/linux/ which wasn't a priority to tackle.  I was just after
stopping the various janitor DM patch submissions from spamming
linux-raid and shli.  So went with the quickest way to express discrete
MD and DM files within the MAINTAINERS file.
