Subject: [PATCH 3/5] KVM: s390: Use kvm_get_vcpu() instead of open-coded access
Date: Fri,  5 Nov 2021 19:20:59 +0000	[thread overview]
Message-ID: <20211105192101.3862492-4-maz@kernel.org> (raw)
In-Reply-To: <20211105192101.3862492-1-maz@kernel.org>

As we are about to change the way vcpus are allocated, mandate
the use of kvm_get_vcpu() instead of open-coding the access.
