Excellent. This is what the world has been waiting for. The full power of shared memory on z/VM will be visible: A single copy of a file in memory, regardless of how many processes or virtual machines are using it. No wasted I/O operations and no wasted memory.
The benefits you can get from this are impressive, and required for running a lot of Linux guests.
Be aware this is very early development and we still need to learn about what it can do. Exploiting this uses portions of CP that have not been used in this way before, and there are plenty of situations where it becomes counter productive.
