Subject: [PATCH 6/7] KVM: mmu: remove ASSERT(vcpu)
Date: Wed, 2 Oct 2013 16:56:15 +0200 [thread overview]
Message-ID: <1380725776-14948-7-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1380725776-14948-1-git-send-email-pbonzini@redhat.com>
Because ASSERT is just a printk, these would oops right away.
The assertion thus hardly adds anything.
