[Qemu-block] [PATCH 0/3] Fix qcow2+luks corruption introduced by commit 8ac0f15f335 |
Date: |

Commit 8ac0f15f335 accidently broke the COW of non changed areas
of newly allocated clusters, when the write spans multiple clusters,
and needs COW both prior and after the write.
This results in 'after' COW area beeing encrypted with wrong
sector address, which render it corrupted.
