Minstrel has long since proven its worth.

Just a quick note: a while ago, somebody proposed
(http://lkml.iu.edu/hypermail/linux/kernel/1202.3/02307.html) a
enhanced version of this algorithm that would, according to the related
research and paper [1], outperform Minstrel in most cases. The patch
was not accepted as comments (mostly related to coding style, but not
only that) weren't addressed by the sender. I then never had the time
to seriously look into it. My understanding is that the amended
algorithm would spare some air time compared to Minstrel, and thus it
could provide marginally better performance.

So, maybe somebody is interested in looking into that. Otherwise, yes,
let's drop it.

They can add it back if needed - looks like this was some academic paper
and they weren't really interested in submitting it to mainline
properly.
