Subject: Re: [PATCH] rust: Do not export generated KASAN ODR symbols

Correct, I don't believe it needs to be backported. `gendwarfksyms` is
the only in-tree tool I am aware of breaking on this. It is possible
someone else is dumping DWARF for all exported symbols, but I don't
know of anyone specific other than Android for kernel ABI monitoring,
who already has this patch in-tree, and does that monitoring on
non-ASAN builds.
