Log message:
	- Fix for:
	198563 ??? clvmd panic in dm_mod:resize_pool while ...
	198659 ??? slab error in kmem_cache_destroy() on m ...
	
	The log server was not informing the device-mapper core of its
	intentions to use its I/O interfaces.  This caused device-mapper
	to prematurely release the resources.
