Bernd Schubert led a session at the 2023 Linux Storage, Filesystem,
Memory-Management and BPF Summit on the intersection
of FUSE
and io_uring. He
works for DDN Storage, which is using FUSE for two network-storage
products; he has found FUSE to be a bottleneck for those filesystems. That
could perhaps be
improved by using io_uring, which is something he has been working on and
wanted to discuss.
