Already asked this but no reply so lemme paste my question again:

"And this document already fulfills its purpose - those two vmcoreinfo
exports are redundant and the first one can be removed.

And now that we agreed that VMCOREINFO is not an ABI and is very tightly
coupled to the kernel version, init_uts_ns.name.release can be removed,
yes?

Or is there anything speaking against that?"
