stubs: Clean up includes Clean up includes so that osdep.h is included first and headers which it implies are not included manually. This commit was created with scripts/clean-includes.

vhost: add vhost_has_free_slot() interface it will allow for other parts of QEMU check if it's safe to map memory region during hotplug/runtime. That way hotplug path will have a chance to cancel hotplug operation instead of crashing in vhost_commit(). Signed-off-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Michael S.

vhost-user: introduce shared vhost-user state When multi queue is enabled e.g. for a virtio-net device, each queue pair will have a vhost_dev, and the only thing shared between vhost devs currently is the chardev. This patch introduces a vhost-user state structure which will be shared by all vhost devs of the same virtio device. Signed-off-by: Tiwei Bie <tiwei.bie@intel.com> Signed-off-by: Michael S.
