I certainly don't object to the split, but I hate the name.

We have uml, umd and umh for user mode {linux, drivers, helper}
respectively.And honestly, I don't see the point in using an obscure
and unreadable TLA for something like this.

I really don't think it would hurt to write out even the full name
with "usermode_driver.c" or something like that, would it?

Then "umd" could be continued to be used as a prefix for the helper
functions, by all means, but if we startv renaming files, can we do it
properly?
