+Subject: [PATCH] Common++: declare align() template inline instead of static
+
+Newer clang (23+) enables -Wunused-template for namespace-scope static
+function templates defined in headers, which fails the -Werror build for
+every translation unit that includes GeneralUtils.h without using
+align():
+
+  Common++/header/GeneralUtils.h:50:38: error: unused function template 'align' [-Werror,-Wunused-template]
+
+Declare it inline instead; that is the correct linkage for a template
+defined in a header and does not trigger the warning.
+
+Upstream-Status: Pending
