In the context of this patch (in progress), it's probably a moot topic
because per comments that Daniel sent, most of the locks in
drm_vblank_wait will become unecessary after I rework the patch
and I won't need to introduce (new) DRM_WAIT_ON_LOCKED any more.
I will, however, *not* convert existing DRM_WAIT_ON to a Linux-centric
function, so I will not be the one to kill (or contribute to the killing
of) the portability of that file. That I leave to someone else ;-).
P.S. If the "fight" starts I will side with the "keep the portability
alive" camp. I have "emotional" ties with other (less widely used)
operating systems. ;-)
