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. [1] Wei Yin, Peizhao Hu, Jadwiga Indulska and Konstanty Bialkowski.
