This is only ever used with unsigned data, so the type itself should be unsigned. Also, PVS Studio's 2016 FreeBSD kernel report correctly identified the following assertion as always being true, so we can drop it: ASSERT3U(dd->dd_space_towrite[i & TXG_MASK], >=, 0); The reason it was always true is because it would do casts to give us unsigned comparisons. This could have been fixed by switching to `ASSERT3S()`, but upon inspection, it turned out that this variable never should have been allowed to be signed in the first place.
