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: ----- static inline int try_module_get(struct module *module){ int ret = 1; <--- error case when !module if (module) { unsigned int cpu = get_cpu(); if (likely(module_is_live(module))) local_inc(&module->ref[cpu].count); else ret = 0; <--- error case put_cpu(); } return ret; <---- } ---- What I understand about the code flow is: -- module live would return the flag stating that this module can be reference and is NOT being removed currently. 1. In case the module pointer passed is invalid (NULL) this function would return 1 (error case) 2. In case the module pointer is OK, and module is currently not being removed, reference count would be incremented and 1 returned (non error case) 3. In case the module pointer is OK, and module reference count can NOT be increased, 0 would be returned (error case). As you can observe from above points, 0 and 1 are returned for error cases. I am a little confused and wondering if there is something which I am missing in this code??. Can anyone help me out with this? Any help would be highly appreciated.
