Huawei Presents Experimental XMFS Cross-Node Shared-Memory Filesystem at LPC 2026
Overview
Huawei engineers presented XMFS, an experimental Linux kernel prototype filesystem, at the Linux Plumbers Conference in Prague on October 5.
The filesystem aims to let applications reach cross-node shared memory on CXL 3.0 or Huawei unified bus servers through standard POSIX file calls.
According to the conference materials, XMFS is a prototype meant to explore the idea rather than a finished filesystem ready to merge. It has not entered formal mainline review, and the code exists only on openEuler, not in the mainline Linux kernel.
