There is also a 'fq' scheduler, but it does not have a manual page.
A good intro 'project' to get up to speed would maybe be to review
this scheduler and write a manual page documenting it - there were also
some kernel posts to dig up from when it was being added as well.
Speaking of - survey time!
Who's using I/O schedulers currently & with what settings??
I had turned off my fq config at some time previously in a failed/misguided
