| After some googling I now believe it was not an interview, but a speech 
| Andrew gave at the '04 Ottawa Linux Symposium. The transscript is here:

| "What else can we do to accommodate all these new requirements and all

| kernel, large changes and a high rate of change without breaking the 
| code base. Across the lifetime of the 2.6 kernel we___ll see many changes 
| as features are added and as we support new hardware. And the rate of 
| change within the kernel has sped up. If we look at the changes in the 
| first six months from the release of 2.4.0 and compare that to the 
| changes from the first six months after the release of 2.6.0, in 2.4 we 
| deleted 22,000 lines and added 600,000 lines. And in 2.6 we deleted 
| 600,000 lines and added 900,000 lines. In the first six months. That___s 
| 1.5 million lines were changed in a 6.2 million-line tree, a 64 MB diff 
| in the first six months of the stable kernel. We changed a quarter of it!"

Is this supposed to be "Andrew Morton" instead of Morris ??
