here is some more info:
in 2.4 kernels, we have
struct kmem_cache_s {
191 /* 1) each alloc & free */
192 /* full, partial first, then free */
193 struct list_head slabs_full;
194 struct list_head slabs_partial;
195 struct list_head slabs_free;
....
whereas in 2.6 we have:
struct kmem_cache_s {
/* 1) per-cpu data, touched during every alloc/free */
struct array_cache *array[NR_CPUS];
unsigned int batchcount;
unsigned int limit;
/* 2) touched by every alloc & free from the backend */
struct kmem_list3 lists;
....
and
struct kmem_list3 {
struct list_head slabs_partial; /* partial list first, better asm code */
struct list_head slabs_full;
struct list_head slabs_free;
kind regards
