Hi,

I'm setting up a raid 5 system and I ran across a bug when reshaping an 
array with a mounted XFS filesystem on it.  This is under linux 2.6.18.2 
and mdadm 2.5.5

You have CONFIG_LBD=n don't you?
  

Yes,

I have CONFIG_LBD=n

...and the patch fixed the problem.

Side Note: I just converted 2 raid0 drives into a 4 drive raid5 array 
in-place, with relative ease.
I couldn't have done it without the work you (and I'm sure others) have 
done. Thanks.
