So this can still be reproduced in 4.9-rc2 by running trinity as a non-root

There's memory corruption all over the place. It is most likely
that trinity is causing this - it's purpose is to trigger corruption
issues, but they aren't always immediately seen. If you can trigger
this xfs trace without trinity having been run and without all the
OK, here is clearer stack output from the run.

Saw on almost all the servers range from x64, ppc64 and s390x with kernel
3.9-rc5 and xfsprogs-3.1.10. Never caught this in 3.9-rc4, so looks like
something new broke this. Log is here with sysrq debug info.
