462 | * XXX rcc - don't know quite what to do with this. I think we can | ||
463 | * just ignore it. The only time that isn't the case is if we allow | ||
464 | * the client to somehow see that quotas have been turned off in which | ||
465 | * we can't allow that to get back until the quotaoff hits the disk. | ||
466 | * So how would that happen? Also, do we need different routines for | ||
467 | * quotaoff start and quotaoff end? I suspect the answer is yes but | ||
468 | * to be sure, I need to look at the recovery code and see how quota off | ||
469 | * recovery is handled (do we roll forward or back or do something else). | ||
470 | * If we roll forwards or backwards, then we need two separate routines, | ||
471 | * one that does nothing and one that stamps in the lsn that matters | ||
472 | * (truly makes the quotaoff irrevocable). If we do something else, | ||
473 | * then maybe we don't need two. | ||
