I think it would be pretty much required. Otherwise stack traces are
going to be very very painful.
In fact, I'm starting to think that Willy is right: we should use
hashes for the "real" symbol name, and have demangled names for
printing, and at no point would the kernel actually want or need to
have the nasty mangled names.
(This wouldn't be rust-specific - using hashes for module linking
sounds like a good diea for C code as well, even if the de-mangled
names for printing are then the regular ones)
Anybody interested in looking into that? It would make this "big
kernel symbols" patch immaterial.
