+For example, a future version of herd7 might not work with the model
+in this release. A compatible model will likely be made available in
+a later release of Linux kernel.

+If you absolutely need to run the model in this particular release,

+klitmus7 is independent of the model provided here. It has its own
+dependency on a target kernel release where converted code is built
+and executed. Any change in kernel APIs essential to klitmus7 will
+necessitate an upgrade of klitmus7.
+
+If you find any compatibility issues in klitmus7, please inform the
+memory model maintainers.
