I have now investigated further, and both the current and previous 
version of Busybox will build without patching the kernel headers, when 
using my custom Busybox config. If I try to build Busybox with an allyes 
config it will fail. Nothing has changed, I have just found out that my 
specific Busybox config will work without patching the kernel headers.

Are there any reasons for me to patch the kernel headers now that I 
found out Busybox will build anyway? Could other applications require 
the headers to be patched?
