Description:
The kernel
samepage merging (KSM) subsystem works by finding pages in memory with
the same contents, then replacing the duplicated copies with a single,
shared copy. KSM can improve memory utilization in a system, but has some problems as well. In two memory-management-track sessions at the 2025
Linux Storage, Filesystem, Memory-Management, and BPF Summit, Mathieu
Desnoyers and Sourav Panda proposed improvements to KSM to
make it work better for specific use cases.
