Announcing a new -ck release, 4.19-ck1 with the latest version of the Multiple Queue Skiplist Scheduler, version 0.180. 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 4.18-ck1, there are a number of minor accounting fixes, and I've since dropped BFQ being enabled by default. I've been less than impressed with its latency over the last two kernel releases, and recommend people use another I/O scheduler.
EDIT: Apparently patch 0008 has one hunk that is out of place. It still should work fine even if this fails to apply. I don't know why git was happy with that part of the patch...
