Minor fixes will be provided if they > prove to be necessary. I'm not applying this. You're turning inline increments and decrements of the existing memory limits into indirect function calls. That imposes a new non-trivial cost, in fast paths, even when people do not use your feature. Make this evaluate into exactly the same exact code stream we have now when the memory cgroup feature is not in use, which will be the majority of users. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
