As discussed in the virtio-blk dataplane start/stop thread, the
various transports contain a lot of similar/identical boilerplate
code for setting up ioeventfds. This makes the code hard to follow.
Let's drag all of the common handling into the virtio-bus layer,
hopefully reducing both the boilerplate code and the number of
indirections.
This RFC patchset is the result of hacking this up quickly, and I
was rather surprised that it did not die immediately on my s390
system (which is all I 'tested'). So be warned :)
Feedback about the approach and the interface would be good.
Cornelia Huck (6):
virtio-bus: common ioeventfd infrastructure
virtio-bus: have callers tolerate new host notifier api
virtio-ccw: convert to ioeventfd callbacks
virtio-pci: convert to ioeventfd callbacks
virtio-mmio: convert to ioeventfd callbacks
virtio-bus: remove old set_host_notifier callback
