Yes, it was you, sorry. For sure, we should added Requested-by. ( I had cherry-picking from other my branch where I didn't add Requested-by and just not double- check before send to xen-devel ) Could you please add Requested-by during the merge? Thank in advance! ~ Oleksii

constant_test_bit() is functionally the same as generic_test_bit(), so constant_test_bit() can be dropped and replaced with generic_test_bit().
