A couple of thoughts: - Please cc linux-mm@kvack.org on this patchset and anything else which impacts MM. - It's a bit strange to create new infrastructure which has but a single call site. Please tell us much more about "there was also request/interest so there will be new comers" to set minds at ease. Who/where are these possible new callsites and when can we expect to see that code?
