What's the base for this patch? (I'm missing the ancestor for drm_gem.c)

error paths you do not modify user inputs. In
particular, consider EINTR where the usual pattern (e.g. drmIoctl) is
do {
err = ioctl(fd, SUBMIT, arg);
} while (err == -EINTR);
If you modify the in fence before you consume it, you can't recreate it
after handling the signal.
