There are a few exception to this licence, however: a few sources herein are distributed according to the GNU General Public License, version 2. You'll find a copy of the license in /usr/src/linux/COPYING, and in other places in your filesystem. The affected source files are: pci/pci_skel.c tty/tiny_serial.c tty/tiny_tty.c usb/usb-skeleton.c The files in ./pci ./tty and ./usb inherit the GPL from the kernel sources, as most of their code comes straight from the kernel (usb-skeleton.c being part of the kernel source tree directly.)
