This new command shows the information of a VirtQueue element.
[Note: Up until v10 of this patch series, virtio.json had many (15+)

most of these enums were removed and replaced with string literals.

It's too costly to write all the BAT to the disk. Let the flush function

Alexander Ivanov (8):
parallels: Out of image offset in BAT
When an image is opened, data_end field in BDRVParallelsState
is setted as the biggest offset in the BAT plus cluster size.
If there is a corrupted offset pointing outside the image,
the image size increase accordingly. It potentially leads
to attempts to create a file size of petabytes.

nvme_irq_assert() only does useful work when cq->irq_enabled is true.
nvme_irq_deassert() only works for pin-based interrupts. Avoid calls
into these functions if we are sure they will not do useful work.
This will be most useful when we use eventfd to send interrupts. We
can avoid the unnecessary
When the new option 'irq-eventfd' is turned on, the IO emulation code
signals an eventfd when it want to (de)assert an irq. The main loop
eventfd handler does the actual irq (de)assertion. This paves the way
for iothread support since QEMU's interrupt emulation is not thread
safe.
Asserting and d
When irqfd is enabled, we bypass QEMU's irq emulation and let KVM to
directly assert the irq. However, KVM is not aware of the device's MSI-x
masking status. Add MSI-x mask bookkeeping in NVMe emulation and
detach the corresponding irqfd when the certain vector is masked.
Signed-off-by: Jinhao Fan
Use KVM's irqfd to send interrupts when possible. This approach is
thread safe. Moreover, it does not have the inter-thread communication
overhead of plain event notifiers since handler callback are called
in the same system call as irqfd write.

The gluster protocol driver used to parse URIs (filenames) but was
extended with a richer JSON syntax in commit 6c7189bb29de
("block/gluster: add support for multiple gluster servers"). The gluster
