Subject: [PATCH v2 09/15] KVM: x86: hyper-v: Stop shadowing global 'current_vcpu' variable
Date: Tue, 26 Jan 2021 14:48:10 +0100 [thread overview]
Message-ID: <20210126134816.1880136-10-vkuznets@redhat.com> (raw)
In-Reply-To: <20210126134816.1880136-1-vkuznets@redhat.com>
'current_vcpu' variable in KVM is a per-cpu pointer to the currently
scheduled vcpu. kvm_hv_flush_tlb()/kvm_hv_send_ipi() functions used
to have local 'vcpu' variable to iterate over vCPUs but it's gone
now and there's no need to use anything but the standard 'vcpu' as
an argument.
