What this function is doing is to ensure that the number of shadow pages

For a given vcpu, kvm_apic_match_dest() will tell you whether
the vcpu in the destination list quickly. Drop kvm_calculate_eoi_exitmap()
and use kvm_apic_match_dest() instead.

Thanks for the FYI, Alex. When we pushed this patch upstream, there was a
corresponding patch to igbvf that was pushed at the same time. With this patch,
the VFs detect the zero address and generate a random MAC address themselves.
The reason for this change is to make the VFs play nicely with u

Currently, vs->vs_endpoint is used indicate if the endpoint is setup or
not. It is set or cleared in vhost_scsi_set_endpoint() or
vhost_scsi_clear_endpoint() under the vs->dev.mutex lock. However, when
we check it in vhost_scsi_handle_vq(), we ignored the lock.

In commit 365a7150094 ([SCSI] virtio-scsi: hotplug support for
virtio-scsi), hotplug support is added to virtio-scsi.
This patch adds hotplug and hotunplug support to tcm_vhost.
You can create or delete a LUN in targetcli to hotplug or hotunplug a
LUN in guest.
