yep i spotted that when i was reading the mail back after i send it :)
i kind of wanted to fix it but i assumed most would see its a typo and
didnt wnat to spam.

the main point i wanted to convay was that nvdimm-p is being standarised
by JEDEC and will be using there unit definitions rather then the IEC
definitions typically used by block storage.

thanks for giving me the opertunity to calrify :)
