I guess we could have a block of pm_qos requests pre-allocated statically and re-use them. In practice there will not be more than a handful of requests ever. Dynamic allocation does seem like a bit of a waste. The calling code will have to store a pointer to your structure anyway, you may as well have them provide the whole structure. -- Arve Hjønnevåg -- 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/
