That's a 2.6.4 patch which generates 100% rejects.

But still, if that patch helped and didn't throw a billion might_sleep()
and people were using preemptible kernels then we have a lock_kernel()
problem. A suitable fix would be to make sure all the locking's tight and
to convert DRM to use unlocked_ioctl.
