	udev           : 10-dm.rules.in 11-dm-lvm.rules 

Log message:
	Use "nowatch" udev rule for known inappropriate devices.
	
	For now, this is just a precaution. Normally, all the other (non-dm) rules
	should check DM_UDEV_DISABLE_OTHER_RULES_FLAG and therefore avoid setting
	any inotify watches as well. But let's make sure.
	
	Support for final assignment of the "nowatch" rule (the use of ":=") will
	appear in next udev release, v160. This should also work in previous udev
	versions but the setting won't be sealed so any further OPTIONS="watch" will
	always prevail there.
	
	We may want to add more specific "nowatch" rules later if needed.
