nit: 'TO' sounds way too much like timeout... TP? You even use 'to' as
shorthand for timeout in the next patch.

itself is no longer a good description of its purpose. This patch

This patch adds the timeout support in other futex types to TO

This patch series update the kernel-docs.txt file, removing broken links, adding

IMHO, after this patch series, kernel-docs.txt will be in a better shape and
could be useful to help new Kernel developers by providing them some extra
