[$] A new swap abstraction layer for the kernel
Swapping may be a memory-management technique at its core, but its
implementation also involves the kernel's filesystem and storage layers.
So it is not surprising that a session on the kernel's swap abstraction
layer, led by Chris Li at the 2024 Linux Storage,
Filesystem, Memory-Management and BPF Summit, was held jointly by all
three of those tracks. Li has some ambitious ideas for an improved
subsystem, but getting to a workable implementation may not be easy.
