Changes
-------

Revision 1:
  Don't let the ioctl interface drop a suspended device.

Revision 2:
  Initialize the clone-info's index to the original bio's index.
  Required to properly handle stacking DM devices. [Kevin Corry]

Revision 3:
  Get rid of the old __MOD_* functions for the newer module api.  This
  also allows the modules to be unloaded. [Greg KH]

Revision 4:
  Use a rw_semaphore in dm_target.c rather than a rwlock_t, just to keep
  in line with dm.c

Revision 5:
  Call dm_put_target_type() *after* calling the destructor.

Revision 6:
  Remove explicit return at the end of a couple of void functions.

Revision 7:
  printk tgt->error if dm_table_add_target() fails.

Revision 8:
  Just return an error from the error targets map function, rather than
  erroring the buffer_head.

Revision 9:
  Export dm_table_get_mode()
