The only way you can get a lot of collision is if you count the same thing multiple times which is not a useful configuration. A single monitoring tool only needs a single event once. While multiple processes may be configuring multiple events at the same time, they will not start them at the same time which also prevents collisions. -Andi -- [email protected] -- Speaking for myself only -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
