Could you try the attached patch? Ok. That is a part of the problem. The other issue that I saw while testing is that the new slab allocator fails on 64 bit non NUMA platforms because the bootstrap does not work right. The size of struct kmem_list3 may become > 64 bytes (with preempt etc on which increases the size of the spinlock_t) which requires an additional slab to be handled in a special way during bootstrap. I hope I will have an updated patch soon. -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org. For more info on Linux MM, see: http://www.linux-mm.org/ .
