Thanks. After spending a good chunk of my life tracking down fsx-linux problems in fsblock and mm code, I can't say I envy you :) It's a great test to run though (especially syncing and dropping caches because that hits writeback and bypasses caches far far more than fsx ever does on its own). Let me know if you need me to test any patches. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
