printk_ratelimited() not compiling

Hey Joe,
So I thought printk_ratelimited would be perfect for an issue I'm
having, but when I tried using it, replacing a printk I had, I got the
following:

fs/namei.c:1075: error: variable â_rsâ has initializer but incomplete type
fs/namei.c:1075: error: unknown field âintervalâ specified in initializer
fs/namei.c:1075: warning: excess elements in struct initializer
fs/namei.c:1075: warning: (near initialization for â_rsâ)
fs/namei.c:1075: error: unknown field âburstâ specified in initializer
fs/namei.c:1075: warning: excess elements in struct initializer
fs/namei.c:1075: warning: (near initialization for â_rsâ)
fs/namei.c:1075: error: storage size of â_rsâ isnât known
fs/namei.c:1075: warning: unused variable â_rsâ


Thinking the issue was ratelimit.h wasn't included I tried that, but
got:

Yuck.

Am I missing something obvious, or did something get broken after this went in?

thanks
