[PATCH 5.10 27/29] KVM: x86: nSVM: restore int_vector in svm_clear_vintr

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Maxim Levitsky <mlevitsk@xxxxxxxxxx>

[ 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.
