Like I said, it is our default license.

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 > > thanks, > > greg k-h
