11  * The percpu allocator handles both static and dynamic areas.  Percpu
12  * areas are allocated in chunks which are divided into units.  There is
171 /* chunks which need their map areas extended, protected by pcpu_lock */
386  * pcpu_next_fit_region - finds fit areas for a given allocation request
451  * Metadata free area iterators.  These perform aggregation of free areas
749 	/* iterate over free areas and update the contig hints */  in pcpu_block_refresh_hint()
1052  * skip over blocks and chunks that have valid free areas.
1110  * free areas, smaller allocations will eventually fill those holes.
1837 	/* clear the areas and return address relative to base address */  in pcpu_alloc()
1954 	 * areas can be scarce.  Destroy all free chunks except for one.  in __pcpu_balance_workfn()
2157  * static percpu areas are not considered.  For those, use
2365  * static areas on architectures where the addressing model has
2378  * for vm areas.
2385  * percpu areas.  Units which should be colocated are put into the
2386  * same group.  Dynamic VM areas will be allocated according to these
