IIUC, most file system I/O is actually initiated by a buffer cache manager in the VM subsystem. At that level, I think it would be quite difficult to relate a dirty page to properties of the process that had done the original write(). So, "SCHED_FIFO to disk" might be limited to raw (unbuffered) I/O. Perhaps that is fine for the scenario you envision. -- joq
