By ignoring interests of someone who does not coopearte with the
community we encourage people to cooperate with the community.

The symbols quoted below are have absolutely nothing to do with KDB
ever. They are pieces of code that you should only use in very
exceptional circumpstances, or you risk breaking the kernel in strange
and mysterious ways.
Beyond that there are modules with GPL compatible licenses. That is the
only kind of module that the kernel license allows.

A capability that no one else can use, and that generates support
requests that can not be supported is not developing more capabilities
for the Linux system. It is denying those of us who ask for repayment
in code, our compensation. It is theft.
