. unmap device drivers from dmap when PM signals they are dead . new null-io function (no_dev_io) to fill in for io functions of unmapped drivers . driver (process number) of unmapped drivers is NONE instead of 0 (a valid process number) IS: . print mutable flag of dmap table too FS changes require sync() to be done 'manually' (currently by reboot/shutdown) at shutdown time; could be caught by SIGTERM in the future.
