Convert all create[_singlethread]_work() users to the new
alloc[_ordered]_workqueue(). This conversion is mechanical and

Incorrect device area lengths are being passed to device_area_is_valid().
The regression appeared in 2.6.31-rc1 through commit
754c5fc7ebb417b23601a6222a6005cc2e7f2913.With the dm-stripe target, the size of the target (ti->len) was used
instead of the stripe_width (ti->len/#stripes). An example of a
consequent incorrect error message is:device-mapper: table: 254:0: sdb too small for target

Add .iterate_devices to 'struct target_type' to allow a function to be
called for all devices in a DM target. Implemented it for all targets
except those in dm-snap.c (origin and snapshot).(The raid1 version number jumps to 1.12 because we originally reserved
1.1 to 1.11 for 'block_on_error' but ended up using 'handle_errors'
instead.)Signed-off-by: Mike Snitzer

Change dm_unregister_target to return void and use BUG() for error
reporting.dm_unregister_target can only fail because of programming bug in the
target driver. It can't fail because of user's behavior or disk errors.This patch changes unregister_target to return void and use BUG if
someone tries to unregister non-registered target or unregister target
that is in use.This patch removes code duplication (testing of error codes in all dm
targets) and reports bugs in just one place, in dm_unregister_target. In
some target drivers, these return codes were ignored, which could lead
to a situation where bugs could be missed.Signed-off-by: Mikulas Patocka
