[Xen-devel] [PATCH v8 05/11] libxl: introduce libxl__device_disk_add

[Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx>]

Introduce libxl__device_disk_add that takes an additional
xs_transaction_t paramter.
Implement libxl_device_disk_add using libxl__device_disk_add.


Changes in v7:

- implement libxl__device_disk_add in libxl.c.
