--- Comment #7 from royvandervegt at gmail.com ---
Wouldn't that be cfb_imageblit as reported by perf report?

`45.27%  test     [kernel.vmlinux]  [k] cfb_imageblit`

If not, can you explain how I can narrow down where the time is spent in the
ioctl by adding debugging output? Do I have to compile my own kernel with added
printfs?
