To submit project 1, we will basically ask you to do the same thing
 that "real" software distributions do in the unix world -- create a
 patch. A patch is a file that notes differences between two files
 or directories. This file can be created via the diff command, and
 be used via the patch command. We encourage you to look up the man
 pages for both of these. We have also provided a link on the resource
 page with more information about these commands.

 In order to create the patch, assume that a "clean" version of the
 kernel (i.e. what you get when you untar the distribution with *no*
 changes) is in the directory /usr/src/linux, and your own modified
 kernel is in /usr/src/mylinux.

 Use the command

 diff -rcP /usr/src/linux /usr/src/mylinux > /tmp/diffout

 The /tmp/diffout file now contains all the information that the patch
 commands needs to transform a clean version of the linux kernel in
 our machine to the modified kernel you had created. Before you
 execute this command, we do suggest that you use make clean or make
 mrproper to remove all the executables, since we are only interested
 in the changes you make to the sources.

 You will submit at least 2 files -- the file that has the output
 of the diff command, and a README file. The README file should contain
 all the information we need to evaluate your project, including such
 mundane stuff as who is in your group, and what kernel version you used.
 If there are any files that you had to change outside the kernel source,
 please submit them as well, with explanations/instructions in the README
 file.
