Description

Originally filed by Max Grossman:

retain birth time info for ZFS holes to avoid unnecessary sends of holes.
Currently, birth_time=0 implies a hole. This optimization will retain birth
time info for holes so that info on where the holes are will only need to be
transmitted in one incremental send, not in every single one following the hole
being created.
