Thank you Mr. Slava and Adam for introducing our research.

If I was given an opportunity, I would like to share and discuss
- A case of memory tiering solution for CXL memory, Samsung SMDK, which
works across userspace and kernelspace : why and how
- Some lessens learned from Industry while CXL integration
- Proposal for possible Linux MM expansions for CXL memory

Regarding FM topic, I'm also interested in what we should supports for CXL
3.0 and later topology.

All the best
Kyungsan
