Actually the second copy is from your tree
(git://git.kernel.org/pub/scm/linux/kernel/git/dledford/rdma.git#for-next),
Leon's trees are empty (relative to Linus' tree).  I guess when you
rebased and squashed things, you forgot to reset your for-next tag, so
I got the old version of your tree as well as the rebased version via
Linus' tree.
