[PATCH 0/2] sched/urgent: zero_vruntime fixes
Posted by Peter Zijlstra 5 hours ago
Hi!

Slightly modified and with a changelog on patches from the thread here:

  https://lkml.kernel.org/r/CANDhNCr3ooATiBgcnq8CAZ+AwzvmHeoKhjvfy=awF1RKFHydCA@mail.gmail.com

Where John found stress-ng-yield made mainline sad.

I have retained the tested-by tags even though I've slightly modified the
patches; holler if you disagree. Local testing shows its good, and my VM was
very quick to panic once I had the right ingredients.

Testing ran well overnight! Thank you again for chasing all of these
edge cases down so fast!
