Note, BTW, there's also a locking issue. Typically, we must make sure
the fbcon (which may be running another CPU) have finished doing whatever
it was doing before returning, and we don't get any mode change or
whatever ioctl initiated thing at that moment (or be in the middle of
doing it).
Right now, my code assumes any operation on the fbdev is protected by
the console sem. However, looking at the console & fbmem code, that is
not always true. Typically, userland ioctls in fbmem aren't, and vt.c
may call into consoles in some cases without holding it neither.
That should probably be fixed, though I haven't had time to work on
it yet.
Ben.
