Yeah you can't just use most pseudo-code in kerneldoc because it's
interpreted as raw .rst. So would need some .rst quoting of some sorts to
make it render correctly.

Usually for pseudo-code I go with blockquotes (started with :: at the end
of the previous line, plus indenting), that gives you also a nice
fixed-width font and everything.

Aside from the hyperlink stuff plain English works best in the text parts.
