Usually, yeah. It would be really nice to do this another way (also for scalability, keeping a large subtree locked is bound to to lead to more contention). -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
