11  * The percpu allocator handles both static and dynamic areas.  Percpu
12  * areas are allocated in chunks which are divided into units.  There is
177 /* chunks which need their map areas extended, protected by pcpu_lock */
411  * pcpu_next_fit_region - finds fit areas for a given allocation request
476  * Metadata free area iterators.  These perform aggregation of free areas
797 	/* iterate over free areas and update the contig hints */  in pcpu_block_refresh_hint()
1100  * skip over blocks and chunks that have valid free areas.
1155  * free areas, smaller allocations will eventually fill those holes.
1881 	/* clear the areas and return address relative to base address */  in pcpu_alloc()
1996 	 * areas can be scarce.  Destroy all free chunks except for one.  in pcpu_balance_free()
2345  * static percpu areas are not considered.  For those, use
2553  * static areas on architectures where the addressing model has
2566  * for vm areas.
2573  * percpu areas.  Units which should be colocated are put into the
2574  * same group.  Dynamic VM areas will be allocated according to these
