Yes we could do this but I am traveling a bit right now. Sorry not that responsive. It will not be strictly correct since a fetch or write could occur from a different cpu and thereby kick out a cacheline. But that is minor I think. The main issue is that this makes this_cpu_read/write different from other this_cpu operations which guarantee that these are "per cpu atomic" in the sense that they are either completely executed or not. But that is mostly important for this_cpu_ ops that are RMV operations like this_cpu_inc(). -- 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/
