Um, this looks like a pointless change and for the worse; Even at -O1
the compiler will reduce strlen(constant) to just its result and for
code like printf("%d\n", sizeof("1234567")) produce code like:

	movl	$7, %esi
	movl	$.LC0, %edi
	movl	$0, %eax
	call	printf

And (though tastes differ) I think the sizeof() variant is less
readable. The strlen(_PATH_something) idiom is common in other parts
of the kernel outside GEOM.

In short - why was this done?
