[Xen-devel] [PATCH 05/14] libxl: disks: expose new "script" parameter for external block scripts

[Ian Jackson <ian.jackson@xxxxxxxxxxxxx>]

This is not currently implemented.  Applications setting it to
anything but NULL will cause an error.  Code to set it from xl
configuration files will appear later in this series.
