Yes, of course. But my point was not if they *can* be dereferenced but rather
if *in the kernel, do want or not to use 'naked' __seg_gs qualified variable*.
In other words, do we want to be warned if someone, somewhere try to
dereference such qualified variable without using the accessor function?
And I think the answer to this question should be 'yes'.
