Extended
attributes (xattrs) provide a way to attach key/value metadata to
inodes—files, directories, and the like—in a filesystem. As with many
Linux filesystems, the FUSE filesystem
supports xattrs. In a filesystem-track session at the 2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit, FUSE maintainer Miklos
Szeredi led a discussion about caching xattrs in kernel memory; he would
like to create some common infrastructure that could be used by FUSE and
shared with other filesystems.
