From: Yong Zhang on
When try to use the new API pr_*_ratelimited(), I got the opposite outcome.
After some checking, I find print_ratelimited() misunderstand the return
value of __ratelimit(). So I fix it in this patchset and also annotate
__ratelimit() for later user.

I mark patch 3 with RFC because I'm afraid I misunderstand the intention,
Ingo, can you please take a look at it? You know that change is introduced
by edaac8e3167501cda336231d00611bf59c164346.

Yong Zhang (3):
ratelimit: annotate ___ratelimit()
kernel.h: fix wrong usage of __ratelimit()
ratelimit: Fix return value when fail to get lock
