Hi, Joe,

Thanks for the patch. I think that is a good idea.

For your patch. I think you need a changelog for each patch.

It seems that the binary representation of UUID can be little-endian
(used by most kernel components) or big-endian (defined by RFC4122, used
in network?). Maybe we should consider about that.

In fact, I find there are many different UUID/GUID definitions in
kernel, such as that in efi, many file systems, some drivers, etc. It
seems that every kernel components need UUID/GUID has its own
definition, so I think we should unify all the UUID/GUID definitions in
kernel too. The file attached is a draft unified UUID/GUID definition,
with byte-order issue in mind.

Any comment?

Best Regards,
Huang Ying
