A new xfstests that really hammers on transaction aborts (generic/495 I think?) uncovered a lot of random issues. Some of these were introduced with the new delayed refs rsv patches, others were just exposed by them, such as the pending bg stuff. With these patches in place I stopped getting all the random leftovers and WARN_ON()'s when running whichever xfstest that was and things are much smoother now. Thanks, Josef
