If the documentationis wrong, and something is relying on the current implementation, thenthis patch might actually break things.> Signed-off-by: Cruz Julian Bishop <cruzjbishop@gmail.com>> --->  drivers/staging/android/logger.c |    4 ++-->  1 file changed, 2 insertions(+), 2 deletions(-)> > diff --git a/drivers/staging/android/logger.c b/drivers/staging/android/logger.c> index 226d8b5..925df5c 100644> --- a/drivers/staging/android/logger.c> +++ b/drivers/staging/android/logger.c> @@ -298,11 +298,11 @@ static inline int is_between(size_t a, size_t b, size_t c)>  {>  	if (a < b) {>  		/* is c between a and b? */> -		if (a < c && c <= b)> +		if (a < c && c < b)>  			return 1;>  	} else {>  		/* is c outside of b through a? */> -		if (c <= b || a < c)> +		if (c < b || a < c)>  			return 1;>  	}A couple of other improvements could be done here. The function shouldreally return bool, inline is unnecessary (the compiler is smart enoughto do that for us), and we can simplify the logic a bit too:static bool is_between(size_t a, size_t b, size_t c){	if (a < b)		swap(a, b);	return (a < c && c < b);}~Ryan`
