I have some errands to run for awhile.
Probably a revert today and another patch set tomorrow
might be best.
This seems to work and doesn't cause any extra state to be
instantiated when !CONFIG_PRINTK. What do you think?
#ifdef CONFIG_PRINTK
#define WARN_ON_RATELIMIT(condition, state) \
WARN_ON((condition) && __ratelimit(state))
#define __WARN_RATELIMIT(condition, state, format...) \
({ \
int rtn = 0; \
if (unlikely(__ratelimit(state))) \
rtn = WARN(condition, format); \
rtn; \
})
#define WARN_RATELIMIT(condition, format...) \
({ \
static DEFINE_RATELIMIT_STATE(_rs, \
DEFAULT_RATELIMIT_INTERVAL, \
DEFAULT_RATELIMIT_BURST); \
__WARN_RATELIMIT(condition, &_rs, format); \
})
#else
#define WARN_ON_RATELIMIT(condition, state) \
WARN_ON(condition)
#define __WARN_RATELIMIT(condition, state, format...) \
({ \
int rtn = WARN(condition, format); \
rtn; \
})
#define WARN_RATELIMIT(condition, format...) \
({ \
int rtn = WARN(condition, format); \
rtn; \
})
#endif
