参数：

类型参数名称
struct kmem_cache *s
3338  BUILD_BUG_ON - break compile if a condition is true(PERCPU_DYNAMIC_EARLY_SIZE < The largest kmalloc size supported by the SLAB allocators is* 32 megabyte (2^25) or the maximum allocatable page order if that is* less than 32 MB * sizeof(structkmem_cache_cpu))
3345  cpu_slab等于__alloc_percpu - allocate dynamic percpu area*@size: size of area to allocate in bytes*@align: alignment of area (max PAGE_SIZE)* Equivalent to __alloc_percpu_gfp(size, align, %GFP_KERNEL).
3348  如果非cpu_slab则返回:0
