I can make the wording more weaselly:

 We strive to follow the Linux kernels coding style so it's recommended
 to run the kernel's ./scripts/checkpatch.pl on new patches.

I added this reference because on the older iterations of these test
divergence from the kernel coding style was pointed out and I've fixed
them in this iteration.
