Every link is preceded by various letters and numbers in square brackets. The letter "C" identifies patches that modify Kconfig files, which contain the help texts and configuration options displayed by "make menuconfig", "make xconfig" and similar tools during kernel configuration. "D" is used for patches that modify the documentation available under Documentation/ in the kernel branch. "N" identifies changes which create a new file. The numbers provide a rough idea of the patch size: For instance, "1" is used for changes between 10 and 20 KBytes including comment, "2" for patches between 20 and 30 KBytes; changes without a number are less than 10 KBytes, while patches marked "9" are 90 KBytes or more.
