The problem is, are you sure this is a variable? or just a constant? or just "alias" (grr, probably not the right name...it's the one you use in DEFINE). When you're sure it's indeed variable AND not considered dead variable during gcc optimization (I might be wrong here, so don't take it for granted), the symbol should exist in the kernel image. -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
