	libdm          : libdevmapper.h 
	udev           : 13-dm-disk.rules 

Log message:
	Remove 'last_rule' from udev rules.
	
	'last_rule' option has been removed from udev (version >= 147).
	
	From now on, we require foreign rules to check and honor
	ENV{DM_UDEV_DISABLE_OTHER_RULES_FLAG} instead. Foreign
	rules should be skipped totally when this flag is set.
