IMHO, the best version of the test is the one which cause a kernel crash.
So your have got the best one. But as far as Jan already mentioned this
is likely core mm/timer issue, not XFS specific one.
Google points me that code affected was changed here https://lkml.org/lkml/2015/3/26/14
Likely that you can trigger the crush w/o your patches. Is it correct?
You can try to fix original bug, or simply migrate patches to some
recent stable kernel version.
