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.
