And same breath,here zcopy is No message from user ;-)
ZCOPY is otherwise often tied with RDMA directly.
Renaming churns are not that useful and I definitely agree
with what Dave said if it was renaming change to the
existing code like what you are suggesting with 'rdma'
Anyways I don't want to contest this too much since I can
follow that code and know what each does and means :-)
The comment was long term readability perspective for
some one completely new reading the code and being able to
distinguish the different modes.

Santosh
