Name	Describe
hibernate_preallocate_memory	hibernate_preallocate_memory - Preallocate memory for hibernation image
enough_free_mem	gh_free_mem - Check if there is enough free memory for the image.
node_dirtyable_memory	de_dirtyable_memory - number of dirtyable pages in a node@pgdat: the node Return: the node's number of pages potentially available for dirty* page cache. This is the base value for the per-node dirty limits.
lruvec_lru_size	lruvec_lru_size - Returns the number of pages on the given LRU list.@lruvec: lru vector@lru: lru to use*@zone_idx: zones to consider (use MAX_NR_ZONES for the whole LRU list)
allow_direct_reclaim
sum_zone_node_page_state	Determine the per node value of a stat item. This function* is called frequently in a NUMA machine, so try to be as* frugal as possible.
zoneinfo_show_print
__zone_watermark_ok	Return true if free base pages are above 'mark'. For high-order checks it* will return true of the order-0 watermark is reached and there is at least* one free page of a suitable size. Checking now avoids taking the zone lock
zone_watermark_ok
zone_watermark_fast
zone_watermark_ok_safe
show_free_areas	Show free area list (used inside shift_scroll-lock stuff)* We also calculate the percentage fragmentation
