Well, I thought about this. But looking at the source (it's pretty
straight forward) there doesn't seem to be a way for this to happen
since it's only a single thread. Maybe if there's some kind of
race condition that could alter the sequence of malloc calls, but
otherwise everything will be allocated in exactly the same order.
Of course, this is just if the alignment change would be in the
user space side.
Even if it's not ordering allocations the same in kernel memory,
I would think that the drm code would always attempt to allocate
aligned blocks.
