md_iostat_ does not distinguish disks when run with multiple raids

[oneiros-de]

I have two md raid5:

md0 : active raid5 sdc1[7] sdb1[4] sdd1[6] sda1[5]
      5860505856 blocks super 1.0 level 5, 128k chunk, algorithm 2 [4/4] [UUUU]
      bitmap: 3/15 pages [12KB], 65536KB chunk

md1 : active raid5 sdc2[2] sdb2[1] sda2[0] sdd2[4]
      2928158976 blocks super 1.0 level 5, 128k chunk, algorithm 2 [4/4] [UUUU]
      bitmap: 0/8 pages [0KB], 65536KB chunk

But md_iostat does not get the right disks for these arrays:

> sudo munin-run md_iostat_md0 config
graph_title IOstat for md0
graph_args --base 1024 -l 0
graph_vlabel blocks / ${graph_period} read (-) / written (+)
graph_category disk
graph_info This graph shows the I/O to and from block devices comprising the raid5 device md0.
graph_order dev8_0_read dev8_0_write  dev8_4_read dev8_4_write  dev8_1_read dev8_1_write  dev8_3_read dev8_3_write  dev9_1_read dev9_1_write 
> sudo munin-run md_iostat_md1 config
graph_title IOstat for md1
graph_args --base 1024 -l 0
graph_vlabel blocks / ${graph_period} read (-) / written (+)
graph_category disk
graph_info This graph shows the I/O to and from block devices comprising the raid5 device md1.
graph_order dev8_0_read dev8_0_write  dev8_4_read dev8_4_write  dev8_1_read dev8_1_write  dev8_3_read dev8_3_write  dev9_0_read dev9_0_write 

The same devices are reported for both arrays.
