Changes
-------

Revision 13:
  Give each device its own io mempool to avoid a potential
  deadlock with stacked devices.  [HM + EJT]

Revision 14:
  Let the persistent/non persistent arg to the snapshot constructor
  be case insensitive. [Heinz Mauelshagen]

Revision 15:
  queue_io() was checking the DMF_SUSPENDED flag rather than the new
  DMF_BLOCK_IO flag.  This meant suspend could deadlock under load.

Revision 16:
  dm_suspend(): Stop holding the read lock around the while loop that
  waits for pending io to complete.

Revision 17:
  Add a run_task_queue(&tq_disk) to encourage pending io to flush
  when we're doing a dm_suspend().
