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. _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
