pcpu_chunk_map

Name:pcpu_chunk_map_bits - helper to convert nr_pages to size of bitmap*@chunk: chunk of interest* This conversion is from the number of physical pages that the chunk* serves to the number of bits in the bitmap.

Proto:static inline int pcpu_chunk_map_bits(struct pcpu_chunk *chunk)

Type:int

Parameter:

struct pcpu_chunk *	chunk

**Caller**
Name	Describe
pcpu_next_fit_region	pcpu_next_fit_region - finds fit areas for a given allocation request@chunk: chunk of interest@alloc_bits: size of allocation@align: alignment of area (max PAGE_SIZE)@bit_off: chunk offset@bits: size of free area Finds the next free region that is
pcpu_find_block_fit	pcpu_find_block_fit - finds the block index to start searching@chunk: chunk of interest@alloc_bits: size of request in allocation units@align: alignment of area (max PAGE_SIZE bytes)@pop_only: use populated regions only* Given a chunk and an
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_init_md_blocks
pcpu_alloc_first_chunk	pcpu_alloc_first_chunk - creates chunks that serve the first chunk@tmp_addr: the start of the region served@map_size: size of the region served* This is responsible for creating the chunks that serve the first chunk
pcpu_alloc_chunk
chunk_map_stats	Prints out chunk state. Fragmentation is considered between* the beginning of the chunk to the last allocation.* All statistics are in bytes unless stated otherwise.
