--- Comment #2 from Konstantin Belousov <kib at FreeBSD.org> ---
(In reply to Bulat from comment #1)
Earlier assignment is performed only under invariants, i.e. in the debugging
kernel.  Later one is for the normal control flow.

So yes, for the invariants-enabled kernel the second assignment is excessive,
but there is no point of optimizing for INVARIANTS, which performs lot of
algorithmically unneeded work to make more robust checks.
