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?
