[Qemu-devel] [PATCH block-next 0/3] qemu-img check/qcow2: Allow fixing refcounts

[Kevin Wolf]

A prerequisite for a "QED mode" in qcow2, which doesn't update the refcount
table except on clean shutdown, is that refcounts can be repaired when the
image is opened the next time after a crash.

This series adds a qemu-img check option that doesn't only check, but also
tries to fix the errors that it found.

  qemu-img check -r for repairing images
  qemu-img check: Print fixed clusters and recheck
  qcow2: Support for fixing refcount inconsistencies
