## Summary
At the 2026 Linux Plumbers Conference, Will Deacon presented a discussion on optimizing kernel stacks to save memory. This initiative responds to a global shortage of memory chips, which has increased the focus on reducing overall system memory consumption.

## The push for memory efficiency
- Kernel stacks are a specific area of memory consumption being re-examined.
- The motivation stems from the worldwide shortage of memory chips.
- The discussion took place during the memory-management microconference at the Linux Plumbers Conference.
