So the annotation of > the rwsem functions is redundant. Remove it. Ok, this bisect makes much more sense. Thomas, Peter, please revert d123375425d7df4b6081a631fc1203fceafa59b2. We cannot compile UML with -mregparm=3 it would cause a lot of trouble. It would break 32bit UML on 64bit and also on older 32bit systems like RHEL5. -- Thanks, //richard -- 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/
