We spent four years on that. It was also done in a very careful and precise manner starting with SMP that gave the same guarantees as non SMP for the 2.0 kernel tree, then moving on to relaxing guarantees in certain places -as they were audited- for 2.2 and with 2.4 increasing the coverage to all major points of contention except the scsi layer
