[PATCH v2 0/2] qemu-img: fix getting stuck in infinite loop on in-chain rebase

[Andrey Drobyshev]

v1 -> v2:

  * Avoid breaking the loop just yet, as the offsets beyond the old
    backing size need to be explicitly zeroed;
  * Amend the commit message accordingly;
  * Alter the added test case to take the last zeroed cluster into
    consideration.

Andrey Drobyshev (2):
  qemu-img: rebase: stop when reaching EOF of old backing file
  qemu-iotests: 024: add rebasing test case for overlay_size >
    backing_size
