Therefore, if a sysfs file is being read or written to the module * which created it must still exist. It is therefore safe to use * try_module_get() on module sysfs store / read ops. * * One of the real values to try_module_get() is the module_is_live() check * which ensures that the caller of try_module_get() can yield to userspace * module removal requests and gracefully fail if the module is on its way out. * * Returns true if the reference count was successfully incremented. */extern bool try_module_get(struct module *module);
