    vfio: Split virqfd into a separate module for vfio bus drivers · 71be3423
    Alex Williamson authored
    An unintended consequence of commit 42ac9bd1 ("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.
