    dasd device driver changes:
     - After a state change interrupt restart all running i/o on queue
       and reset device timer.
     - Improve some debug messages.
     - Lower timeout of reserve/release/steal_lock to 2 seconds.
     - Fix BIODASDPSRD ioctl.
     - Replace ro_flag, use_diag_flag and disconnect_error_flag words by bits.
     - Use BLKPG_DEL_PARTITION ioctl instead of a call to delete_partition because
       delete_partition is not an exported function. Since dasd_destroy_partitions
       can't do blkdev_get because dasd_open would fail, keep the block device
       open as long as partitions exist. This in turn requires a different
       approach to the open vs. offline race.
