[dm-devel] [PATCH] call dm_lib_release/exit explicitly in multipath-tools

[Kiyoshi Ueda <k-ueda ct jp nec com>]

Hi Christophe,

multipath-tools should call dm_lib_release() and dm_lib_exit() 
before it returns.  Then, libdevmapper will call update_devs()
and finalize the device node operation which creates
/dev/mapper/<map_name>.

This patch may not be needed if the latest libdevmapper of the
device-mapper CVS is used, since in the latest version, 
dm_lib_exit() calls dm_lib_release() and dm_lib_exit() is called
by default when the program returns.

Regards,
Kiyoshi Ueda
