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
