The last use of paravirt_disable_iospace() was removed in 2015 by
commit d1c29465b8a5 ("lguest: don't disable iospace.")
Remove it.
Note the comment above it about 'entry.S' is unrelated to this
but stayed when intervening code got deleted.

openat is useful to avoid needing to construct relative paths, so expose

Is that really needed? You're saving tcp.sk_cb.prot, so you could just
call peer->tcp.s

Abstract vhost worker operations (create/stop/wakeup) into an ops

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 function
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.

The VHOST_NEW_WORKER requires the inherit_owner
