Modified files:
	lib/filters    : filter.c 

Log message:
	Remove constant expression check
	
	"result_independent_of_operands: ((dev->dev & 0xfff00UL) >> 8) ==
	18446744073709551615UL /* -1 */ is always false regardless of the values
	of its operands (logical operand of if)."
	
	'dev->dev' is set in dev-cache.c _insert() and it's not expectable
	st_rdev would have '-1'
	
	This code has been introduced with drbd support commit and code never
	worked - so eliminated.
