Your understanding is fundamentally wrong. The Linux-syscall-note
explicitly does not cover the kernel interface, which is what kernel
modules use.

I'm not discussing this further, though. I'm just going to say that
Red Hat Legal has consistently told Fedora this over the years, and I
do not expect this to change for CentOS.
