commit 01ca29f0b17a50a94b0e232ba276c32e95d80ae3 Author: Dario Faggioli <dfaggioli@xxxxxxxx> AuthorDate: Wed Aug 3 12:14:01 2022 +0200 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Wed Aug 3 12:14:01 2022 +0200 sched: dom0_vcpus_pin should only affect dom0 If dom0_vcpus_pin is used, make sure the pinning is only done for dom0 vcpus, instead of for the hardware domain (which might not be dom0 at all!).
