If the size of memory region that is being set up is the same as before, we don't have to do memory and layer busy checks.

Well, I wouldn't allow code like that if it was a new ioctl, but if, as you say, the old omapfb worked that way, then I think it's better to do things the same way. I can see no harm in it, so I'll apply. Tomi
