Instead of messing with all this I suggest that we just add a jiffies
based timeout to the BO when we can clear the flag. For kernel BOs this
timeout is just infinity.
Then we check in amdgpu_cs_bo_validate() before generating the
placements if we could clear the flag and do so based on the timeout.
The idea for this patch was to save the memory and CPU cycles needed for
that approach.
But when we clear the flag on the end of the move we already moved the
BO to visible VRAM again.
Only on after the next swapout/swapin cycle we see an effect of that change.
Is that the intended approach?
