Description
When Josh was reviewing a recent kernel rbd patch he pointed
out that a variable named "obj_size" was misleading because it
might not reflect the full size of an object (because it could
be clipped by parent_overlap).
That highlighted an underlying problem--that the code was
assuming the size of a "full" parent read request was the
size of a complete object, without taking the parent_overlap
into account.
This needs to be fixed.
