Path for the problem
When the user loads multipath with invalid arguments, there is memory leak and module reference count leak.
dmsetup create --table '0 2 multipath 0 0 1 1 round-robin /dev/sdh' mpath0
After the command, the reference count on dm_round_robin is 1, although the module is unused, and it prevents further removal of the whole dm subsystem.
