linux - Why Linux kernel memory subsystem is named slab

Question

Slab is of an object-caching kernel memory subsystem. But why call it slab?

I have a deep search. From Jeff Bonwick's paper, the name slab derives from one of the allocator's main data structures, the slab. So, why the data structure is called slab?

Answer 1

板坯，在通常的用法中，是指一块大而扁平的固体材料块。以此类推，slab 分配器管理大的、连续的内存块，将它们分成更小的块进行分配。
