[PATCH] scripts/kwboot: Fix normalizing timeval

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



If tv.tv_usec is 1000000 the structure needs normalizing, too. So the
right check would be:

	if (tv.tv_usec >= 1000000) {
		...

But as normalizing doesn't destroy anything even for smaller values,
just do it unconditionally to simplify a bit.
