[PATCH RFC] vhost: optimize interrupt enable/disable
...t matters.
Signed-off-by: Michael S. Tsirkin <mst at redhat.com>

It seems an obvious optimization so I queued this up
already.

[PATCH 0/2] vhot-net: Use kvm_memslots instead of vhost_memory to translate GPA to HVA
From: Hongyong Zang <zanghongyong at huawei.com>
Vhost-net uses its own vhost_memory, which results from user space (qemu) info,
to translate GPA to HVA. Since kernel's kvm structure already maintains the
address relationship in its member *kvm_memslots*, these patches use kernel's
kvm_memslots directly without the need of initialization and maintenance of
vhost_memory.

[PATCH 0/2] adding tracepoints to vhost
To help in vhost analyzing, the following series adding basic tracepoints to
vhost. Operations of both virtqueues and vhost works were traced in current
implementation, net code were untouched. A top-like satistics displaying script
were introduced to help the troubleshooting.
TODO:
- net specific tracepoints?
