I've been unable to reproduce the error in ~24 hours of testing. Normally, I'd hit the error within an hour of testing on a single run. I've made three separate runs, and let the last run proceed overnight. I'll keep using these patches, and let you know if anything turns up. Thanks for all your work on this patch set. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
