Hello everyone, when i'm going through the linux src for net drivers, i found a strange line of code. i wanted to register a bottom half handler for the net irq. in net/profiles.h, there is a function called net_profile_register and some other functions. this was declared as extern inline void net_profile_register. i could'nt understand what extern inline void means. when i use this function in my driver(of course using the macro NET_PROFILE_REGISTER), while insmod, it says net_profile_register unresolved external symbol. please any one help me on this, thanks, babu -- Kernelnewbies: Help each other learn about the Linux kernel.
