From 71be3423a62be548c56bab5b818e1a1383e659d2 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Tue, 17 Mar 2015 08:33:38 -0600 Subject: vfio: Split virqfd into a separate module for vfio bus drivers An unintended consequence of commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in VFIO generic code") is that the vfio module is renamed to vfio_core so that it can include both vfio and virqfd. That's a user visible change that may break module loading scritps and it imposes eventfd support as a dependency on the core vfio code, which it's really not. virqfd is intended to be provided as a service to vfio bus drivers, so instead of wrapping it into vfio.ko, we can make it a stand-alone module toggled by vfio bus drivers. This has the additional benefit of removing initialization and exit from the core vfio code.
