I think when all this was discussed alongside the clk_prepare/clk_unprepare stuff, that yes, it was decided that clk_set_rate() was non-atomic only. And yes, that is most definitely the case, because the first thing clk_set_rate() does is take a mutex - which will trigger a might_sleep() complaint if ever called from an atomic context. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
