vhost: replace vhost_workqueue with per-vhost kthread
Replace vhost_workqueue with per-vhost kthread. Other than callback argument change from struct work_struct * to struct vhost_work *, there's no visible change to vhost_poll_*() interface. This conversion is to make each vhost use a dedicated kthread so that resource control via cgroup can be applied. Partially based on Sridhar Samudrala's patch. * Updated to use sub structure vhost_work instead of directly using vhost_poll at Michael's suggestion. * Added flusher wake_up() optimization at Michael's suggestion. Changes by MST: * Converted atomics/barrier use to a spinlock. * Create thread on SET_OWNER * Fix flushing Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Michael S.
