(by my reading) the problem is that determining what the C ABI is relies on a C parser. If a module depends on an API, genksyms checks if the ABI has changed and won't load the module as a result (or more broadly, it could also use content addressing to look at the body of the function). It seems like the solution is to use DWARF info to determine that but it has to be backwards compatible because previous implementations relied on the parsed C code and not the DWARF symbol info.
