[$] Management of volatile CXL devices

Compute
Express Link (CXL) memory is not like the ordinary RAM that one might
install into a computer; it can come and go at any time and is often not
present when the kernel is booting. That complicates the management of
this memory. During the memory-management track of the 2025 Linux Storage,
Filesystem, Memory-Management, and BPF Summit, Gregory Price ran a session
on the challenges posed by CXL and how they might be addressed.
