Subject: [PATCH 3/7] KVM: x86 emulator: drop dead pf injection in emulate_popf()
Date: Mon, 22 Nov 2010 17:53:23 +0200	[thread overview]
Message-ID: <1290441207-4250-4-git-send-email-avi@redhat.com> (raw)
In-Reply-To: <1290441207-4250-1-git-send-email-avi@redhat.com>

If rc == X86EMUL_PROPAGATE_FAULT, we would have returned earlier.
