[Qemu-devel] [PATCH 0/3] mirror: Fix behavior for zero byte image |

The current behavior of mirroring zero byte image is slightly different from
non-zero image: the BLOCK_JOB_READY event is skipped and job is completed
immediately. This is not a big problem for human user but only makes management
software harder to write. Since we are focusing on an good API instead of UI,
let's make the behavior more consistent and predictable.
The first patch fixes the behavior. The following two patches add test case for
the involved code path.
Thanks for Eric Blake to report this!
