This patch set does not define a new format, but piggy backs on top of
the existing <securityfs>/ima/binary_runtime_measurements list. The
prefixed buffer header includes a version, so that if in the future we
need to modify the format, we would be able to.
In terms of the prefixed header, how would you define the fields:
version, buffer size, number of measurements?
