Subjectproblem about try_module_get(struct module *module)
Hi,
I have a problem about the try_module_get function, I don't know if someone
removed the module just AFTER line 372, then what happens? Because in this
situation, the variable module will be incorrect, and module_is_live
function will
lead to unpredicatable behaviour.

368 static inline int try_module_get(struct module *module)
369 {
370 int ret = 1;
371
372 if (module) {
373 unsigned int cpu = get_cpu();
374 if (likely(module_is_live(module)))
375 local_inc(&module->ref[cpu].count);
376 else
377 ret = 0;
378 put_cpu();
379 }
380 return ret;
381 }

Best wishes to all,
rmingming
