Introduce a new config knob `CONFIG_VHOST_ENABLE_FORK_OWNER_IOCTL`,
to control the availability of the `VHOST_FORK_FROM_OWNER` ioctl.
When CONFIG_VHOST_ENABLE_FORK_OWNER_IOCTL is set to n, the ioctl
is disabled, and any attempt to use it will result in failure.

Add a new UAPI to configure the vhost device to use the kthread mode.
The userspace application can use IOCTL VHOST_FORK_FROM_OWNER
to choose between owner and kthread mode if necessary.
This setting must be applied before VHOST_SET_OWNER, as the worker
will be created in the VHOST_SET_OWNER functi
This patch reintroduces kthread mode support in vhost,
It also introduces struct vhost_worker_ops to abstract
worker create/stop/wakeup operations.
* Bring back the original vhost_worker() implementation,
and renamed to vhost_run_work_kthread_list().
* Add cgroup support for the kthread

The vhost now uses vhost_task and workers as a child of the owner thread.
While this aligns with containerization principles, it confuses some
legacy userspace applications, therefore, we are reintroducing kthread
API support.
Introduce a new parameter to enable users to choose between kthread and
In commit 6e890c5d5021 ("vhost: use vhost_tasks for worker threads"),
the vhost now uses vhost_task and operates as a child of the
owner thread. This aligns with containerization principles.
However, this change has caused confusion for some legacy
userspace applications. Therefore, we
