Upstream patch for this issue
DLM is not part of the core kernel in rhel 4 and is provided as part of the
cluster products so changing product name and flags to be appropriate.
The code in rhel-4's version of dlm is quite different from rhel-5. I am not sure if the changes in device_write (dlm_write in this version) needs the change. Please verify. Thanks.
