Re: try_module_get code understanding

I was going through try_module_get function in include/linux/module.h file (2.6.22 stock kernel) - which is like: - static inline int try_module_get(struct module *module){ int ret = 1; --- error case when !module if (module) { unsigned int cpu = get_cpu();

Re: try_module_get code understanding

Then what is return value if my module tries to 'get' a module which does not exist (and is a module, not in-built)? . Is it '1' ? Or am I imagining a hypothetical scenario which would not exist? That is not supposed to happen. After a module got unloaded there shouldn't be any objects around

try_module_get code understanding

Dear List, I agree that this issue certainly doesn't require to be in this list (rightful place being kernewbies) but I tried that and got no response - so trying my luck here. I was going through try_module_get function in include/linux/module.h file (2.6.22 stock kernel) - which is like:
