Wow, you are fast. :) Sounds and looks good to me.
I guess we should assign the meta structure only after all values are filled in? Otherwise we could get partial reads from a possible user?
Did you already test to put a lookup-call to the in-kernel mounter, if we use some special partition table uuid identifier for root=? That would be nice to see, if all that works as expected, and we can get to the data we collect.
