Hi,

Hi,
+//#define SPICE_QEMU_CHAR_USE_IOCTL
Why is this disabled?
Does it depend on the chardev patches from Amit?
There was a long discussion that concluded we don't want IOCTL's at all,
and that there should be some other mechanism for connection state
communication between the two sides.

Ok, I think this might actually make everyone happy, but I've been

This patchset adds support for the SCSI WRITE SAME with unmap command,
which allows reclaiming free space from a backing image.
The user facing implementation is pretty complete, but not really
efficient because the underlying bdrv_discard implementation doesn't
use the aio implementation yet.
Add a new bdrv_discard method to free blocks in a mapping image, and a new
drive property to set the granularity for these discard. If no discard
granularity support is set discard support is disabled.

Support discards via the WRITE SAME command with the unmap bit set, and
tell the initiator about the support for it via the block limit and the
new thin provisioning EVPD pages. Also fix the comment which incorrectly

Add support to discard blocks in a raw image residing on an XFS filesystem

hole punching mechanisms can be added when they become available.

Create a trivial interface to track whether the machine has been
