This points to a mutex to serialize with MMU notifiers during page table

I don't think mixing the VM code into this is a good idea. Instead we
Well first of all don't mess with the VM internals outside of the VM code.
Then why would we want to expose this through the IOCTL interface? We

This patch intorduces new UAPI/IOCTL for usermode graphics

the graphics driver to add a graphics work queue for it. The
