this is correct.  you need a kernel bump when ever the kernel
ABI changes.

hiding stuff inside an alloc doesn't really help much when the
kernel code needs to access the structure anyway, unless you
also hide all accesses to the structure inside functions.

that said, it's probably a good idea anyway.
