[Qemu-block] [PULL 01/23] block: failed qemu-img command should return non-zero exit code

[Kevin Wolf]

From: Xu Tian <address@hidden>

If the backing file cannot be opened when doing qemu-img rebase, the
variable 'ret' was not assigned a non-zero value, and the qemu-img
process terminated with exit code zero. Fix this.
