As part of on ongoing effort to perform more automated testing and provide more tools for individual developers to validate their patches before submitting, we are trying to make our code "clang-format clean". My hope is that once we have fixed all of our style "quirks", developers will be able to run clang-format on their patches to help avoid silly formatting problems and ensure their changes fit in well with the rest of the SELinux kernel code.
