From: Josh Poimboeuf Date: Mon, 13 Apr 2026 08:59:31 +0000 (-0700) Subject: objtool/klp: Don't report uncorrelated functions as new X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=76eb0f8639fbc6bcc0e7c1ca649c456bfebc4d5c;p=thirdparty%2Flinux.git objtool/klp: Don't report uncorrelated functions as new Clang LTO uses __UNIQUE_ID() to generate some uniquely named wrapper functions, like initstubs. If they're uncorrelated, prevent them from being reported as new functions and included unnecessarily. Note that dont_correlate() already includes prefix functions, so prefix functions are still being ignored here.
