Hi, I've a pattern similar to this in sysfs: /sys/.../mykobj/myattr_group/attr. And I've some different attr groups, but I'm willing to group also the get/set functions and recognize at runtime which kobj,group,and attribute is called inside the functions. But, if I'm not wrong the attribute functions are called: static ssize_t some_attribute_set(struct kobject *kobj, struct container_attribute *attr, const char *buf, size_t count) And I can get the "mykobj" name with kobj->name, and attribute names by attr->attr.name. I'm missing only the myattr_group name... anyone has a clue of how can I access this? Just for completeness, I'm working on a 2.6.38 kernel, and I'm declaring the groups this way: struct container_attribute { struct attribute attr; ssize_t (*show)(struct kobject *, struct container_attribute *, char *); ssize_t (*store)(struct kobject *, struct container_attribute *, const char *, size_t); }; static struct attribute *lot_of_attrs[] = { first_attribute.attr, and_so_on.attr, NULL, }; static struct attribute_group my_attr_group_0 = { .name = "myattr_group_0", .attrs = lots_of_attrs, }; And adding to my kobject this way: retval = sysfs_create_group(mykobj, &my_attr_group_0); Thanks, bye! -- -gaspa-
