The fbcondecor helper should perform all ioctls with >+ origin set to FBCON_DECOR_IO_ORIG_USER. >+ >+modechange >+---------- >+ The kernel issues this command on a mode change.

These ioctls are to be used by both the userspace helper >+(called only by the kernel) and userspace configuration tools (run by the users). >+ >+The fbcondecor helper should set the origin field to FBCON_DECOR_IO_ORIG_KERNEL >+when doing the appropriate ioctls.
