The Filesystem in
Userspace (FUSE) subsystem provides a way to service filesystem
requests from a user-space server, which moves the format-handling code out
of the kernel.  The FUSE server can use the io_uring
facility for better performance, but Bernd Schubert is concerned that
memory is being wasted because the current implementation has a single,
large buffer size that is excessive for small I/O operations.  He led a discussion on that topic
in the filesystem track of the 2026 Linux Storage,
Filesystem, Memory Management, and BPF Summit in Zagreb, Croatia.
