The above mentioned commit accidentally made it so we encrypt the second COW area using the physical cluster offset of the first area. The problem is that offset_in_cluster in do_perform_cow_encrypt can be larger that the cluster size, thus cluster_offset will no longer point to the start of the cluster at which encrypted area starts. Next patch in this series will refactor the code to avoid all these assumptions. In the bugreport that was triggered by rebasing a luks image to new, zero filled base, which lot of such writes, and causes some files with zero areas to contain garbage there instead.
