This is more a comment to 906c508afdca (\"sysfs: attribute_group: allow registration of const bin_attribute\") than to this patch:
Why have you named the pointer `bin_attrs_new` and not something meaningful e.g. `bin_attrs_const`? I know, it is already in the kernel, but I would highly recommend to rename the pointer in another patch.
