返回类型:unsigned long
参数:
类型 | 参数 | 名称 |
---|---|---|
struct zone * | zone |
名称 | 描述 |
---|---|
show_mem | |
zoneinfo_show_print | |
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 |
nr_free_zone_pages | r_free_zone_pages - count number of pages beyond high watermark*@offset: The zone index of the highest zone* nr_free_zone_pages() counts the number of pages which are beyond the* high watermark within all zones at or below a given zone index |
si_meminfo_node | |
show_free_areas | Show free area list (used inside shift_scroll-lock stuff)* We also calculate the percentage fragmentation |
zone_batchsize | |
pageset_set_high_and_batch | |
calculate_totalreserve_pages | alculate_totalreserve_pages - called when sysctl_lowmem_reserve_ratio* or min_free_kbytes changes. |
setup_per_zone_lowmem_reserve | setup_per_zone_lowmem_reserve - called whenever* sysctl_lowmem_reserve_ratio changes. Ensures that each zone* has a correct pages reserved value, so an adequate number of* pages are left in the zone after a successful __alloc_pages(). |
__setup_per_zone_wmarks | |
setup_min_unmapped_ratio | |
setup_min_slab_ratio | |
managed_zone | Returns true if a zone has pages managed by the buddy allocator.* All the reclaim decisions have to use this function rather than* populated_zone(). If the whole zone is reserved then we can easily* end up with populated_zone() && !managed_zone(). |
