Even if the host is somehow using compare to do compare-and-write, the
host should be notified immediately about the compare failure and not
have to wait for the driver to potentially retry the command.

Small typo above, I missed the /1, it should read:

It is useful to have the ability to disable these features for
compatibility with older VMs that don't have these implemented.

Make vhost-user-blk backwards compatible when migrating from older VMs
running with modern features turned off, the same way it was done for
virtio-blk in 20764be0421c ("virtio-blk: set config size depending on the
features enabled")
It's currently impossible to migrate from an older VM with

This patch set attempts to align vhost-user-blk with virtio-blk in
terms of backward compatibility and flexibility.
In particular it adds the following things:
- Ability to disable modern features like discard/write-zeroes.
- Dynamic configuration space resizing based on enabled features,
by reu
No reason to have this be a separate field. This also makes it more akin
to what the virtio-blk device does.

These test cases uses "blkdebug:path/to/config:path/to/image" for
testing. On Windows, absolute file paths contain the delimiter ':'
which causes the blkdebug filename parser fail to parse filenames.

On Windows, the MinGW provided mkstemp() API opens the file with
exclusive access, denying other processes to read/write the file.
Such behavior prevents the QEMU executable from opening the file,
(e.g.: CreateFile returns ERROR_SHARING_VIOLATION).
This can be fixed by closing the
We would have one more place for block_acct_setup() calling, which should
not corrupt original value.

There is a difference in the mkdir() call for win32 and non-win32
platforms, and currently is handled in the codes with #ifdefs.
glib provides a portable g_mkdir_with_parents() API and we can use
it to unify the codes without #ifdefs.
