This memory lives in page-cache/lru, it is visible for shrinker which will unmap these pages for no reason on memory shortage. IOW, aio fools the kernel, this memory looks reclaimable but it is not. And we only do this for migration. Even if this is not a problem, this does not look right. So perhaps at least mapping_set_unevictable() makes sense. But I simply do not know if migration will work with this change. And I should have changes the subject a long ago... So what do you think we should do with the build failure?
