Re: [BLOCK] Unify the seperate read/write io stat fields into arrays

[Chris Wedgwood <cw@f00f.org>]

I wouldn't mind a comment with that:

>  struct disk_stats {
> -	unsigned read_sectors, write_sectors;
> -	unsigned reads, writes;
> -	unsigned read_merges, write_merges;
> -	unsigned read_ticks, write_ticks;
	/* Element 0 is for reads, 1 for writes */
> +	unsigned sectors[2];
> +	unsigned ios[2];
> +	unsigned merges[2];
> +	unsigned ticks[2];
>  	unsigned io_ticks;
>  	unsigned time_in_queue;
>  };
