mmmh.. they should have been here, I mean, in patch 2/3 but it seems
they're gone in patch 1/3 (subject: i/o controller documentation):

Documentation of the block device I/O controller: description, usage,
advantages and design.

I'm pretty sure I did a:
git-commit -s Documentation/controllers/io-throttle.txt
in my local branch (history confirms this), but, anyway, if you think
it's worth it I can fix it and post the patchset again, just let me
know.

Thanks for looking at it!
