There are a lot of ratelimit_state structs used in the kernel. Every printk like <foo>_ratelimited uses a static one. It'd likely be better to reduce the struct ratelimit_state size rather than expand it. burst and printed could probably become s16 or even s8. flags could be u8 until necessary to expand.
