+Upstream status: RHEL only
+
+We don't really need the field names to be globally unique, it is enough
+when they are unique in the given struct. Since structs do not generally
+span mutliple files, using the line number is enough to ensure an unique
+identifier. It means that we can't use two RH_KABI_RENAME macros on the same
+line but that's not happening anyway.
+
+This allows pahole to deduplicate the type info of structs using kABI
+macros, lowering the size of vmlinuz from 26M to 8.5M.
