blkverify: Add block driver for verifying I/O

The blkverify block driver makes investigating image format data
corruption much easier. A raw image initialized with the same contents
as the test image (e.g. qcow2 file) must be provided. The raw image
mirrors read/write operations and is used to verify that data read from...

qcow2: Avoid bounce buffers for AIO write requests

qcow2 used to use bounce buffers for any AIO requests. This does not only imply
unnecessary copying, but also unbounded allocations which should be avoided.

This patch removes bounce buffers from the normal AIO write path. Encrypted...

scsi-generic: add missing reset handler

Ensure that pending requests of a SCSI generic device are purged on
system reset. This also avoids calling a NULL function in lsi53c895a.
The lsi code was recently changed to call the .qdev.reset function.

scsi_bus: fix length and xfer_mode for RESERVE and RELEASE commands

For the RESERVE and RELEASE commands the length must be zero
and xfer_mode must be SCSI_XFER_NONE.

qcow2: Get rid of additional sync on COW

We always have a sync for the refcount update when a new cluster is
allocated. If we move this past the COW, we can save an additional sync.

ide: propagate the required alignment

IDE is a bit ugly in this respect. For one it doesn't really keep track
of a sector size - most of the protocol is in units of 512 bytes, and we
assume 2048 bytes for CDROMs which is correct most of the time.

Second IDE allocates an I/O buffer long before we know if we're dealing...

cutils: qemu_iovec_copy and qemu_iovec_memset

This adds two functions that work on QEMUIOVectors and will be used by the next
qcow2 patches.
