[Qemu-devel] [PULL 10/61] qcow2: Alignment of snapshot table entries |
Date: |

From: Max Reitz <address@hidden>
The qcow2 specification does not explicitly state so far that every
snapshot table entry is aligned to 8 bytes. QEMU, in contrast, does this
alignment, thus it should be properly documented (which this patch
does).
