[Qemu-devel] [PATCH 0/7] block: bdrv_reopen() patches

[Jeff Cody]

These patches are strongly based off Supriya Kannery's original bdrv_reopen()
patches as part of the hostcache series, including the _prepare(), _commit(), 
and
_abort() structure.

Some additions / changes:

* Added support for multiple image reopen transactionally
* Reopen changes are staged into temporary stashes in prepare(),
  and copied over in commit() (discarded in abort()).
* Driver-level reopen file changes are mainly contained in
  the raw-* files.


TODO: The raw-win32 driver still needs to be finished
