From cdea5cadb0ca403b1929f8d29929c0eda0f715d6 Mon Sep 17 00:00:00 2001 From: Song Liu Date: Thu, 5 Mar 2026 15:15:30 -0800 Subject: objtool/klp: Match symbols based on demangled_name for global variables correlate_symbols() will always try to match full name first. If there is no match, try match only demangled_name. In very rare cases, it is possible to have multiple foo.llvm. in the same kernel. Whenever there is ambiguity like this, fail the klp diff.
