[dm-devel] dmsetup export option

[Kay Sievers]

Here is the "export" patch we currently use to import device mapper
properties into the udev event environment.

It looks like this:
  $ dmsetup export luks
  DM_NAME=luks
  DM_STATE=ACTIVE
  DM_TABLE_STATE=LIVE
  DM_OPENCOUNT=0
  DM_LAST_EVENT_NR=0
  DM_MAJOR=254
  DM_MINOR=0
  DM_TARGET_COUNT=1
  DM_TARGET_TYPES=crypt

Alasdair, I remember vaguely while we talked about that at OLS, you
wanted to see that implemented using some other backend functions. Let
me know, if I need to change something.

Thanks,
Kay
