My examples are running on Ubuntu with kernel 4.2. jonsmirl@terra:/work/gm/linux-3.3-fa$ uname -a Linux terra 4.2.0-33-generic #38-Ubuntu SMP Tue Mar 8 22:42:18 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux jonsmirl@terra:/work/gm/linux-3.3-fa$
The linux-3.3-fa prompt is because I am painfully working on an ARM9 vendor kernel when the vendor does not update their code. I am porting features from the current kernel back to their old system. I don't have the source for everything to forward port their code.
