incorrect page aging and the (mistaken) reclaim of
hot pages, but the chance of that should be relatively low.
I'm wondering if this could cause worse-case behavior with TTM? I'm

t writes are always protected by vblank_time_lock (something I
did not verify but that the comment above asserts), then the trailing write
barrier is not required (and the assertion that it is in the comment is
incorrect).
A spin unlock operation is always a write barrier.
