Perhaps this could give a short explanation of why they are marked as
legacy and what the plan is to get rid of them.

Nit: might as well remove the unusual blank line between the closing
brace and the EXPORT_SYMBOL while at it.

The parameters are somewhat oddly wrapped here. Nothing that the patch
introduces, but perhaps low-hanging fruit while at it. There are a few
other occurrences in this file.

I found only minor whitespace nits, feel free to ignore those.
