Looks like it was a wrong fix.
It breaks audit like this:
sudo auditctl -e 0
[   88.400296] audit: error in audit_log_task_context
[   88.400976] audit: error in audit_log_task_context

Error sending enable request (Operation not supported)

when CONFIG_LSM= has "bpf" in it.

KP, Anders,
please take a look.
