Not really without knowing more about how the device will be used and the costs associated with powering it up and down - it's all a question of tradeoffs depending on things like how fast userspace needs a response and the expected usage patterns (many accesses in quick succession, occasional widely spaced accesses...). -- 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/
