Log message:
	Fix for bug:
	199862 - Suspending cluster mirrors can cause indefinite hang
	And is part of a fix for:
	199185 – 'lvconvert' fails to remove device-mapper devices ...
	198555 – mirror log not getting cleared causes new mirror ...
	And is likely to fix:
	199334 – cmirror removal attempt hangs and caused locking ...
	And will certainly help for:
	199498
	198821
	194137
	194125
	199635
	
	All of the above bugs will need to be reexamined when the packages
	are rebuilt.
	
	This fix allows the log server to migrate to other nodes during
	suspension.  This prevents the situation where the log server may
	have it's devices suspended when it recieves a request.  Trying to
	fulfill a log request while devices are suspended will lead to an
	indefinite hang, because I/O will not complete until the devices
	are unsuspended.
