Name:set_pageblock_migratetype

Proto:void set_pageblock_migratetype(struct page *page, int migratetype)

Type:void

Parameter:

Type	Parameter	Name
struct page *	page
int	migratetype

552

If Value for the false possibility is greater at compile time(page_group_by_mobility_disabled && migratetype < MIGRATE_PCPTYPES) Then migratetype = MIGRATE_UNMOVABLE

**Caller**
Name	Describe
init_cma_reserved_pageblock	Free whole pageblock and set its migration type to MIGRATE_CMA.
change_pageblock_range
steal_suitable_fallback	This function implements actual steal behaviour. If order is large enough,* we can steal whole pageblock. If not, we first move freepages in this* pageblock to our migratetype and determine how many already-allocated pages
reserve_highatomic_pageblock	Reserve a pageblock for exclusive use of high-order atomic allocations if* there are no empty page blocks that contain a page with a suitable order
unreserve_highatomic_pageblock	Used when an allocation is about to fail under memory pressure
__isolate_free_page
memmap_init_zone	Initially all pages are reserved - free ones are freed* up by memblock_free_all() once the early boot process is* done. Non-atomic initialization, single-pass.
