+Subject: [PATCH 18/33] [meta-browser] Fix "undefined symbol:
+ PaintOpWriter::SerializedSize<unsigned long>()"
+
+For some reason, clang 14 (currently used on dunfell and kirkstone)
+seems to fail to correctly generate a needed instantiation of
+`cc::PaintOpWriter::SerializedSize<T>()`, and thus the final linking
+step fails with an "undefined symbol" error.
+
+We can fix this by explicitly providing a specialization, which does the
+same thing as the generic implementation.
+
+Upstream-Status: Inappropriate [specific to older versions of clang]
