Browsing some code I found that user-space and kernel-space macros for (un-)packing major/minor device numbers differ. The user-space ones using still the old 16 bit scheme. There was no explaining comment around and most libraries have their own macros anyway so it should not be a problematic UAPI change. So IMHO we could win some coherence in abandon this discrepancy.
Please correct me if I am wrong.
You are wrong, we can't change this api, things will break :(
sorry,
