Hi Dave, I hope the following series is in an acceptable state: I modified the tests in __sk_mem_schedule() in a way that we should still leave the function pretty soon under no pressure conditions.
Also, I managed to remove almost everything tcp related from memcontrol.c: the only thing left is a simple function to calculate the address of the tcp sub-structure in the main memcg structure - I hope this is acceptable, since besides being simple, it is not related to the protocol itself. I also believed that by now, all other comments so far were addressed. Let me know if there are any blocking concerns to this, and I'll address them as soon as I can.
