Then I have no idea what happens here.
The returned pages are identical, only the overhead to allocate them is reduced significantly.
The only other idea I have is that this somehow changes the timing and exposes a bug somewhere else.
You could try to replace the "for (order = min(MAX_ORDER - 1UL, __fls(num_pages)); num_pages;" in ttm_pool_alloc() with "for (order = 0; num_pages;" to get the old behavior.
