Currently the method of dealing with an IO operation on a bus (PIO/MMIO)
is to call the read or write callback for each device registered
on the bus until we find a device which handles it.
Since the number of devices on a bus can be significant due to ioeventfds
and coalesced MMIO zones, this

This is crazy, why would we only test this for PCI_CAP_ID_EXP? If the

This patch adds support for writing to zero refcount clusters. Refcount blocks
are cached in like L2 tables and flushed upon VIRTIO_BLK_T_FLUSH and when
evicted from the LRU cache.
With this patch applied, 'qemu-img check' no longer complains about referenced
clusters with zero reference count

I think we also need to copy and clear this flag on the splice
read path as that takes a direct page reference.

The main goal of the patch is to effectively cap the disk I/O speed or counts
of one single VM.
It is only one draft, so it unavoidably has some drawbacks, if you catch them,
please let me know.
The patch will mainly introduce one global timer and one block queue for each
