Pull audit updates from Paul Moore:
"Four audit patches for v5.17:
- Harden the code through additional use of the struct_size() macro
and zero-length arrays to flexible-array conversions.
- Ensure that processes which generate userspace audit records are
not exempt from the kernel's audit throttling when the audit queues
are being overrun"
