Bug#618463: please backport mdadm-3.2.2-1 to current stable

[pille]

hi,

i've suffered from the same bug and spent the last three days resizing 
the (physical GPT) partitions of my underlying raid6 devices and trying 
to grow the array. i did disk-by-disk rebuilds in order to make mdadm 
notice the new space, but it didn't work.

today i stumbled upon this bug and reviewed the mdadm changelog, which 
fixes this bug. i sucessfully grew the array using the version from 
nightly install CD.

please backport from testing to stable.

thanks
   pille
