The command for live block commit is added, which has the following
arguments:
device: the block device to perform the commit on (mandatory)
base: the base image to commit into; optional (if not specified,
it is the underlying original image)
top: the top image of the commit - all data from inside top down
to base will be committed into base (mandatory for now; see
note, below)
speed: maximum speed, in bytes/sec
Note: Eventually this command will support merging down the active layer,
but that code is not yet complete. If the active layer is passed
in as top, then an error will be returned. Once merging down the
active layer is supported, the 'top' argument may become optional,
and default to the active layer.
The is done as a block job, so upon completion a BLOCK_JOB_COMPLETED will
be emitted.
