From ffb7c77fd5039a01b2534465a2cdf7514f7fc9df Mon Sep 17 00:00:00 2001 From: Sean Christopherson Date: Tue, 15 Feb 2022 11:05:21 -0800 Subject: [PATCH] KVM: sefltests: Use vcpu_ioctl() and __vcpu_ioctl() helpers Use the recently introduced vCPU-specific ioctl() helpers instead of open coding calls to ioctl() just to pretty print the ioctl name.
