The secret to tripping over the bug is run the test until fsstress
fills the filesystem before removing the files. So an error
handling?

I use the test:

#!/bin/sh

ltp/fsstress -z -s 1378390208 -fsymlink=1 -n9999999 -p4 -d /test2
cd /test2
sync
rm -rf *

If your filesystem is smaller, decrease the -n to make the test faster.

I have still not gotten a core, though Michael Semon sent one.

It would be useful if we could wire this up for xfstests
