[$] The MuQSS CPU scheduler

By corbet The scheduler is a topic of keen interest for the desktop user;
the scheduling algorithm partially determines the responsiveness of
the Linux desktop as a whole. Con Kolivas maintains a series of scheduler patch sets
that he has tuned considerably over the years for his own use, focusing
primarily on latency reduction for a better desktop experience. In
early October 2016
, Kolivas updated the design of his popular desktop
scheduler patch set, which he renamed MuQSS. It is an update (and a name
change) from his previous scheduler, BFS, and it is designed to address
scalability concerns that BFS had with an increasing number of CPUs.
