Merge tag 'docs-5.6' of git://git.lwn.net/linux
Pull documentation updates from Jonathan Corbet:
"It has been a relatively quiet cycle for documentation, but there's
still a couple of things of note:
- Conversion of the NFS documentation to RST
- A new document on how to help with documentation (and a maintainer
profile entry too)
Plus the usual collection of typo fixes, etc"
