Subject: [PATCH 0/2] KVM: x86: cleanup and fix userspace interrupt window
Date: Fri, 27 Nov 2020 06:21:12 -0500 [thread overview]
Message-ID: <20201127112114.3219360-1-pbonzini@redhat.com> (raw)
This is my take on the split irqchip bug that David reported. It's a
much more complicated patch, but I think it really gets to the bottom
of the issue and the code is clearer.
