Ouch.
Actually, the alternate patch is the one I had intended to do but for some
reasons didn't.
This one also removes two more lines than it adds, but it's obviously a
bigger patch.
Junio, depending on which one you prefer, add the appropriate
Acked-by: Linus Torvalds <torvalds@xxxxxxxx>
(for Andre's one) or
Signed-off-by: Linus Torvalds <torvalds@xxxxxxxx>
if you take this one.
Linus
