The FamFS file-system being developed by Micron hopes to go upstream for Linux in "early-ish 2026".

For around two years already Micron has been working on FamFS as a new file-system that is special purpose and designed for fabric-attached memory (FAM) needs such as with CXL servers. FamFS over the past year was ported to FUSE for largely operating in user-space but some kernel changes remain.
