Subject: [PATCH 3/7] KVM: selftests: Take vcpu pointer instead of id in vm_vcpu_rm()
Date: Fri, 20 Mar 2020 13:55:42 -0700	[thread overview]
Message-ID: <20200320205546.2396-4-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20200320205546.2396-1-sean.j.christopherson@intel.com>

The sole caller of vm_vcpu_rm() already has the vcpu pointer, take it
directly instead of doing an extra lookup.
