It would be better/more generic if you split copy_from_user_nmi() into init() copy() end() (and some state that checks if the underlying page changes) Then first you don't need the buffer and it could be also be applied to the other cases, like the stack unwinding, where copying everything is likely too slow. -Andi -- 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/
