Normally flags would be bit fields, not values like this.
Also, what's the distinction between RDM and RMRR, and is there a good
reason to use the first here rather than the second?
It's also not clear to me what NO_RDM is meant to be for -- is it
meant to be an assertion that the caller expects the device to have no
RMRRs associated with it?
All concerns what you're raising above just make me realized you're
missing all background info and history changes. So I think if you
really would like to review this series, at least you should take a look
at our previous design and some basic change log, which are mentioned
inside patch #00.
Thanks
Tiejun
