Caller| Name | Describe |
|---|
| constrained_alloc | Determine the type of allocation constraint. |
| shrink_zones | This is the direct reclaim path, for page-allocating processes. We only* try to reclaim pages from zones which will satisfy the caller's allocation* request.* If a zone is deemed to be full of pinned pages then just give it a light |
| throttle_direct_reclaim | Throttle direct reclaimers if backing storage is backed by the network* and the PFMEMALLOC reserve for the preferred node is getting dangerously* depleted. kswapd will continue to make progress and wake the processes* when the low watermark is reached. |
| try_to_free_pages | |
| __node_reclaim | Try to free up some pages from this node through reclaim. |
| prepare_alloc_pages | |
| nr_free_buffer_pages | r_free_buffer_pages - count number of pages beyond high watermark* nr_free_buffer_pages() counts the number of pages which are beyond the high* watermark within ZONE_DMA and ZONE_NORMAL.* Return: number of pages beyond high watermark within ZONE_DMA and |
| nr_free_pagecache_pages | r_free_pagecache_pages - count number of pages beyond high watermark* nr_free_pagecache_pages() counts the number of pages which are beyond the* high watermark within all zones.* Return: number of pages beyond high watermark within all zones. |
| dequeue_huge_page_nodemask | |
| policy_nodemask | Return a nodemask representing a mempolicy for filtering nodes for* page allocation |
| mempolicy_slab_node | Depending on the memory policy provide a node from which to allocate the* next slab entry. |
| mpol_misplaced | mpol_misplaced - check whether current page node is valid in policy*@page: page to be checked*@vma: vm area where page mapped*@addr: virtual address where page mapped* Lookup current policy node id for vma,addr and "compare to" page's* node id |
| fallback_alloc | Fallback function if there was no memory available and no objects on a* certain node and fall back is permitted. First we scan all the* available node for available objects. If that fails then we* perform an allocation without specifying a node |
| get_any_partial | Get a page from somewhere. Search in increasing NUMA distances. |
| set_recommended_min_free_kbytes | |
