[PATCH v11 8/8] vhost: use vhost_tasks for worker threads
...ads of the thing that started
them, not as processes.
So they should show up in 'ps' only when one of the "show threads" flag is set.
But I suspect the fix is trivial: the virtio code should likely use
CLONE_THREAD for the copy_process() it does.
It should look more like "create_io_thread()" than "copy_process()", I think.
For example, do virtio worker threads really want their own signals
and files? That sounds wrong. create_io_thread() uses all of
CLONE_FS|CLONE_FILES|CLONE_SIGHAND|CLONE_THREAD|CLONE_IO
to share much more of the context with the process it is ac...

[PATCH 0/3] vhost: Fix freezer/ps regressions
The following patches made over Linus's tree fix the 2 bugs:
1. vhost worker task shows up as a process forked from the parent
that did VHOST_SET_OWNER ioctl instead of a process under root/kthreadd.
This was causing breaking scripts.
2. vhost_tasks didn't disable or add support for freeze requests.
The following patches fix these issues by making the vhost_task task
a thread under the
