[Qemu-devel] [PATCH v2 0/9] VHDX log replay and write support

[Jeff Cody <jcody@redhat.com>]

This patch series contains the initial VHDX log parsing, replay,
and write support.

v2 changes:  incorporated Fam's review feedback

This will allow an existing log in a VHDX image to be replayed (e.g., a VHDX
image from a Hyper-V host that crashed).  In addition, metadata writes are
enabled through the log.  This allows write support to be enabled for VHDX,
as the BAT can be updated safely via the log journal.

These exact patches are available from github, for testing:

The latest vhdx work (including anything beyond these patches, such as
backing/parent file support) can be found at:
