With the experimental x-nbd-server-add-bitmap command, there was

Having to fire up qemu, then use QMP commands for nbd-server-start
and nbd-server-add, just to expose a persistent dirty bitmap, is
rather tedious. Make it possible to expose a dirty bitmap using
just qemu-nbd (of course, for now this only works when qemu-nbd is
visiting a BDS formatted as qcow2).
We only have one caller that wants to export a bitmap name,
which it does right after creation of the export. But there is
still a brief window of time where an NBD client could see the
export but not the dirty bitmap, which a robust client would
have to interpret as meaning the entire image should

The existing NBD code had a weird split where nbd_export_new()

ui/console.h already includes ui/qemu-pixman.h, just move it there?

We can also use vfio_register_event_notifier() helper in
vfio_intx_enable_kvm to set the signalling associated to
VFIO_PCI_INTX_IRQ_INDEX.

The code used to attach the eventfd handler for the ERR and
REQ irq indices can be factorized into a helper. In subsequent
patches we will extend this helper to support other irq indices.
We test the notification is allowed outside of the helper:
respectively check vdev->pci_aer and VFIO_FEATURE_E
This small series introduces the vfio_register_event_notifier()
helper which allows to set up/tear down the VFIO signalling of eventfd
for ERR, REQ and INTX irq indices.
On top of that, a new irq index is planned to signal DMA faults
in nested mode use case. This would use exactly the same mechani

In vfio_connect_container() the code that selects the
iommu type can benefit from helpers such as
vfio_iommu_get_type() and vfio_init_container(). As
a result we end up with a switch/case on the iommu type
that makes the code a little bit more readable and ready
for addition of new iommu types. Als
Whenever the allocation length of a SCSI request is shorter than the size of the
VPD page list, page_idx is used blindly to index into r->buf. Even though
the stores in the insertion sort are protected against overflows, the same is
not
true of the reads and the final store of 0xb0.
