If the coder doesn't lock his data structures, it doesn't matter _what_ order we execute the list modifications in - different architectures will do different thing with inter-CPU memory ordering, and trying to order memory accesses on a source level is futile.
However, if the list manipulation had some memory barriers added to it...
The people doing the lockless reader RCU stuff could benefit from such an interface. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
