[Qemu-devel] [PATCH 08/15] qemu_ram_alloc: Add DeviceState and name parameters

[Alex Williamson <alex.williamson@redhat.com>]

These will be used to generate unique id strings for ramblocks.  The name
field is required, the device pointer is optional as most callers don't
have a device.  When there's no device or the device isn't a child of
a bus implementing BusInfo.get_dev_path, the name should be unique for
the platform.
