A minor nit...

Sorry to jump in a bit late in this, but... concerning the use of "puts"
the userspace stdio version adds a trailing newline. Thus, to avoid any
confusion, I think the kerneldoc for this should explicitly state that
this does not add a newline.

 * Write string to *data without a trailing newline. Update *data to
 * point at the start of the next string.

This shouldn't be an issue, but it makes the behaviour of it plainly
obvious to the reader.
