My question is why a symbol with same definition shows up in 2.6.23.1-42.fc8 and not in 2.6.18-128.7.1.el5. > > Is there fundamental change in how symbols appear in /proc/kallsyms ? > Brief check using lxr.linux.no, I found no codes that might hide inet_family_ops in your Scientific Linux kernel (I simply assume it's based on 2.6.18 vanilla). So, IMO, there might be one explanation left. Scientific Linux kernel is compiled with CONFIG_KALLSYMS_ALL=n. Reading the related Kconfig help info, I think this is it. Try to check your Scientific Linux kernel .config file. -- regards, Mulyadi Santosa Freelance Linux trainer blog: the-hydra.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
