Pull documentation updates from Jon Corbet:
"A relatively boring cycle in the docs tree. There's a few kernel-doc
fixes and various document tweaks.
One patch reaches out of the documentation subtree to fix a comment in
init/do_mounts_rd.c. There didn't seem to be anybody more appropriate
to take that one, so I accepted it"
