A lot of time device mapper devices leak across mount namespace which docker does not know about and when docker tries to deactivate/delete device, operation fails as device is open in some mount namespace. Create a mechanism where one can defer the device deactivation/deletion so that docker operation does not fail and device automatically goes away when last reference to it is dropped.
