Name:Store a type+offset into a swp_entry_t in an arch-independent format
Proto:static inline swp_entry_t swp_entry(unsigned long type, unsigned long offset)
Type:swp_entry_t
Parameter:
Type | Parameter | Name |
---|---|---|
unsigned long | type | |
unsigned long | offset |
33 | val = type << swapcache pages are stored in the swapper_space radix tree | offset & SWP_OFFSET_MASK |
34 | Return ret |
Name | Describe |
---|---|
alloc_swapdev_block | alloc_swapdev_block - allocate a swap page and register that it has* been allocated, so that it can be freed in case of an error. |
free_all_swap_pages | _all_swap_pages - free swap pages allocated for saving image data.* It also frees the extents used to register which swap entries had been* allocated. |
total_swapcache_pages | |
swap_cluster_readahead | swap_cluster_readahead - swap in pages in hope we need them soon*@entry: swap entry of this memory*@gfp_mask: memory allocation flags*@vmf: fault information* Returns the struct page for entry and addr, after queueing swapin. |
__try_to_reclaim_swap | rns 1 if swap entry is freed |
scan_swap_map_slots | |
swap_alloc_cluster | |
get_swap_page_of_type | The only caller of this function is now suspend routine |
try_to_unuse | If the boolean frontswap is true, only unuse pages_to_unuse pages;* pages_to_unuse==0 means all pages; ignored if frontswap is false |
generic_max_swapfile_size | Find out how many pages are allowed for a single swap device |
zswap_frontswap_store | attempts to compress and store an single page |
