Hi,
I think we all owe a debt of gratitude for Alex's excellent 2+ years of OpenSM,
libibumad, and ibsim maintainership. I hope I can live up to the high standard
Alex set. Thanks for all you've done Alex!

Hi,
I want to announce that starting from today Hal Rosenstock which you are
familiar with, is going to maintain OpenSM, libibumad and ibsim development.
So starting from today his trees should be considered as master

Hi. In case you're interested, I did the NFS/RDMA backports for OFED. I
tested that NFS/RDMA in OFED 3.5 works on kernel 3.5, and also the RHEL
6.3 kernel. However, I did not test it with SRIOV. If you test it
(OFED-3.5-rc6 was released last week), I'd like to know how it goes. Thanks.

This patch enhanced the IB core support for Memory Windows.

Do not enable memory windows allocation for virtual functions.
In addition, add a few safety checks, such as:

* Making sure binding memory window isn't enabled for FMRs, and
that new memory windows are not FMR themselves.
