名称	描述
pcpu_alloc_area	pcpu_alloc_area - allocates an area from a pcpu_chunk@chunk: chunk of interest@alloc_bits: size of request in allocation units@align: alignment of area (max PAGE_SIZE)@start: bit_off to start searching* This function takes in a @start offset to begin
pcpu_free_area	pcpu_free_area - frees the corresponding offset@chunk: chunk of interest@off: addr offset into chunk* This function determines the size of an allocation to free using* the boundary bitmap and clears the allocation map.
pcpu_alloc	pcpu_alloc - the percpu allocator@size: size of area to allocate in bytes@align: alignment of area (max PAGE_SIZE)@reserved: allocate from the reserved chunk if available@gfp: allocation flags* Allocate percpu area of @size bytes aligned at @align
pcpu_balance_workfn	Balance work is used to populate or destroy chunks asynchronously. We* try to keep the number of populated free pages between* PCPU_EMPTY_POP_PAGES_LOW and HIGH for atomic allocations and at most one* empty chunk.
pcpu_setup_first_chunk	pcpu_setup_first_chunk - initialize the first percpu chunk@ai: pcpu_alloc_info describing how to percpu area is shaped@base_addr: mapped address* Initialize the first percpu chunk which contains the kernel static* percpu area
