Package: linux-image-4.9.0-4-amd64
Version: 4.9.65-3
Severity: important
Affects: openafs-modules-dkms

debian/patches/debian/keys-limit-abi-change-in-4.9.59.patch renames
register_key_type to register_key_type_2 without bumping the ABI counter,
breaking OpenAFS kernel modules (package openafs-modules-dkms) built
against 4.9.51.

Symptom:
[   35.911739] openafs: Unknown symbol register_key_type (err 0)
and the module fails to load.
