 Ok, I've recreated the problem in form of a semiautomatic testcase.
 All necessary files (plus the old xfs_repair output) are at:
   http://www.nagilum.de/md/

 After running the test.sh the created xfs filesystem on the raid  
 device is broken and (at last in my case) cannot be mounted anymore.

I think that you should file a bugreport, and provide there the
explanations you have put in there. An automated test case that leads
to xfs corruption is a neat snack for bug squashers ;-)

I wonder however where to report this - the xfs or raid ? Eventually
cross report to both places and write in the bugreport that you are
not sure on which side there is a bug.

best regards

Try adding --run.  or maybe --force.

 As pointed out to when you came up with the idea, we can't do this. A devpath
 is a path to the device and will not necessarily start with /block for block
 devices. It may start with /devices and can be much longer than
 BDEVNAME_SIZE*2  + 10.


When you say will not necessarily can I take that to mean that it
currently does, but it might (will) change??
In that case can we have the patch as it stands and when the path to
block devices in /sys changes, the ioctl can be changed at the same
time to match?

Or are you saying that as the kernel is today, some block devices
appear under /devices/..., in which case could you please give an
example?

Thanks,
