This patch set aimed to get rid of most annoying locks. In case of journalled quota it is dq_iomutex and i_mutex. Patches are simple and clean. Patches make difference between nojournaled/journaled quota modes less significant. And allow us to switch to default journalled quota without performance penalty. There are many other optimizations possible, but they are more intrusive and require wide discussions. -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
