Hmm. I was expecting the CONFIG_TRIM_UNUSED_KSYMS fix to come in from
you too. IOW, this:
https://lore.kernel.org/all/20241214105726.92557-1-masahiroy@kernel.org/
which fixes the "load_utf8() ->symbol_request() -> symbol_get()
returns NULL" case when CONFIG_TRIM_UNUSED_KSYMS is enabled.
Obviously I can apply that patch directly, but the reason I _didn't_
do so was that I was just expecting it to come through the normal
Kbuild tree... Pls advice,
Linus

Sorry, I noticed a case where that patch does not work.
For example, when both consumer and provider of a symbol
are modules,v2 does not solve the issue.
I need to send v3.
