Announcing a new -ck release, 4.20-ck1 with the latest version of the Multiple Queue Skiplist Scheduler, version 0.185. These are patches designed to improve system responsiveness and interactivity with specific emphasis on the desktop, but configurable for any workload.
In addition to a resync from 4.19-ck1 I've extended the runqueue sharing options to all CPUs as well, meaning it can be used in NUMA hardware as a single runqueue if desired.
Merry Christmas, and have a happy new year everyone. May your new year be filled with good health, stable kernels, and more bitcoin adoption and value.
