ELF can do symbol versioning too. But I don't really see a simple way to make normal ELF linking work with a kernel like that. The vmlinux ELF file is long gone by the time the kernel boots -- it needs its own mechanism for managing its symbols anyway; its own internal dynamic linker. I suppose you _could_ make it work from the standard ELF linkage but I don't think it'd be fun. ObMODVERSIONS: Forgot to mention that my makefile hacks for --combine break that completely. It tries to preprocess all the files together with 'gcc -E -D__GENKSYMS__ *.c' -- and you can't do that. -- dwmw2 - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||
