Thanks - and good news.

I'd still like to know how this bug manages to cause a crash (I create an
array that have identical "mdadm -E" and "mdadm -X" output on an x86_64
machine, and couldn't make it crash).

I'll add a Reported-by: and Tested-by: for you and submit to Linus shortly.

A pleasure - specially when I get to work with helpful and responsive
people :-)
