It does, as I just said. The benefit is probably mainly due to the
introduction of loops around device_create_file() calls. The patch
reduces the number of calls (in the binary) from 59 to 20.

Yeah, I'll take a look into this at some point. This should make the
code even more readable and efficient.

Agreed. This was really a quick hack, not meant for inclusion. Maybe I
should have polished it a bit more before I dared sending it. I'll do so
next time, sorry for the noise.
