This would allow some filesystems to report per-mount I/O stats, while leaving CIFS and NFS reporting a different set of per-sb stats. This doesn't sound very clean. There was an effort to create saner and more efficient interfaces for per-mount info. IMO this should be part of that effort instead of overloading the old interface. Thanks, Miklos
