Subject: [PATCH 5.10 27/29] KVM: x86: nSVM: restore int_vector in svm_clear_vintr
Date: Fri, 8 Oct 2021 13:28:14 +0200 [thread overview]
Message-ID: <20211008112717.885608463@linuxfoundation.org> (raw)
In-Reply-To: <20211008112716.914501436@linuxfoundation.org>
From: Maxim Levitsky <mlevitsk@redhat.com>
[ Upstream commit aee77e1169c1900fe4248dc186962e745b479d9e ]
In svm_clear_vintr we try to restore the virtual interrupt
injection that might be pending, but we fail to restore
the interrupt vector.
