Content-Type: text/plain; charset=UTF-8; format=flowed Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org I've understand that major and minor numbers for device is 8-bit size. I've don't understand, WHY? In 2012! (I've just have some discussion about 8-bit counter limitations in context of cloud computing. In middle of 2012!!!!) But seriously, I've done some googling but found no answer why it still just 8 bit size. Is this some serious backward compatibility? Or just there is no one with itch strong enough?
