slab/vmem: introduction to memory management - Pierre Cornet

This talk presents 2 complementary memory management designs used in kernel memory management: slab allocator and vmem allocator. The slab allocator is based on a cache allocation of objects that remain in constructed state between usages. This proves to be space-efficient and fast. The vmem allocator is a general-purpose resource allocator allowing for arbitrary-size allocation and better large object allocation.
