+Code of Conflict
+----------------
+
+The Linux kernel development effort is a very personal process compared
+to "traditional" ways of developing software.  Your code and ideas
+behind it will be carefully reviewed, often resulting in critique and
+criticism.  The review will almost always require improvements to the
+code before it can be included in the kernel.  Know that this happens
+because everyone involved wants to see the best possible solution for
+the overall success of Linux.  This development process has been proven
+to create the most robust operating system kernel ever, and we do not
+want to do anything to cause the quality of submission and eventual
+result to ever decrease.
+
+If however, anyone feels personally abused, threatened, or otherwise
+uncomfortable due to this process, that is not acceptable.  If so,
+please contact the Linux Foundation's Technical Advisory Board at
+<tab@lists.linux-foundation.org>, or the individual members, and they
+will work to resolve the issue to the best of their ability.  For more
+information on who is on the Technical Advisory Board and what their
+role is, please see:
+	http://www.linuxfoundation.org/programs/advisory-councils/tab
+
+As a reviewer of code, please strive to keep things civil and focused on
+the technical issues involved.  We are all humans, and frustrations can
+be high on both sides of the process.  Try to keep in mind the immortal
+words of Bill and Ted, "Be excellent to each other."
