Subject: [PATCH 16/16] KVM: arm64: selftests: Deal with spurious timer interrupts
Date: Thu, 16 Feb 2023 14:21:23 +0000 [thread overview]
Message-ID: <20230216142123.2638675-17-maz@kernel.org> (raw)
In-Reply-To: <20230216142123.2638675-1-maz@kernel.org>
Make sure the timer test can properly handle a spurious timer
interrupt, something that is far from being unlikely.
