This is obvious crap. Explain to me, please, what makes your "GPL compatible"
different from "GPLv2"; at least that would be honest ("we have relicensed
a copy of BSD/GPL code to GPL alone - the license allows that and any
modifications done here are declared GPL-only, so you can't pull them into
the BSD-licensed variants")

"GPL compatible" is not a license; it's a set of licenses. Incidentally,
belonging to that set is irrelevant to legality of including into the kernel,
since GPLv3 a member and it's *NOT* compatible with the kernel license.
since GPLv3 a member and it's *NOT* compatible with the kernel license.
