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

Pls advice, 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. > > Linus
