-Subject: [PATCH 111/126] overload on wakeup
-
-source https://github.com/jplozi/wastedcores
-
-as an experiment, apply the learnings from the wasted-cores paper
-and see how the performance works out. With the data from this we should
-be able to work with Peter and the rest of the scheduler folks on
-a more permanent/elegant solution.
