Like I said, it is our default license. Saeed will change this code to be GPL-only.

I don't remember being asked about it, not in this patch
https://lore.kernel.org/all/20180425203703.568152337@linutronix.de/
and not in this later patch which changed LICENSES/other/ to be
LICENSES/deprecated/
https://lore.kernel.org/all/20190430105130.24500-4-hch@lst.de/

So it is nice that someone decided to deprecate it without notifying users
about such change. It will be better to put Linux-OpenIB to LICENSES/dual/
folder instead.

Our lawyers are perfectly fine with Linux-OpenIB license.

Thanks
