Subject[RFC PATCH 0/8] vhost_tasks: Use CLONE_THREAD/SIGHAND
Date
This patch allows the vhost and vhost_task code to use CLONE_THREAD,
CLONE_SIGHAND and CLONE_FILES. It's a RFC because I didn't do all the
normal testing, haven't coverted vsock and vdpa, and I know you guys
will not like the first patch. However, I think it better shows what
we need from the signal code and how we can support signals in the
vhost_task layer.

Note that I took the super simple route and kicked off some work to
the system workqueue. We can do more invassive approaches:
1. Modify the vhost drivers so they can check for IO completions using
a non-blocking interface. We then don't need to run from the system
workqueue and can run from the vhost_task.

2. We could drop patch 1 and just say we are doing a polling type
of approach. We then modify the vhost layer similar to #1 where we
can check for completions using a non-blocking interface and use
the vhost_task task.
