[Qemu-devel] [PATCH] block-commit: speed is an optional parameter

[Max Reitz]

As speed is an optional parameter for the QMP block-commit command, it
should be set to 0 if not given (as it is undefined if has_speed is
false), that is, the speed should not be limited.

This patch was previously part of the "qemu-img: Implement commit like
QMP" series, but as this is a general bugfix, it has been separated.
