find_get

Name:d_get_page - find and get a page reference*@mapping: the address_space to search*@offset: the page index* Looks up the page cache slot at @mapping & @offset. If there is a* page cache page, it is returned with an increased refcount.

Proto:static inline struct page *find_get_page(struct address_space *mapping, unsigned long offset)

Type:struct page

Parameter:

Type	Parameter	Name
struct address_space *	mapping
unsigned long	offset

**Caller**
Name	Describe
stack_map_get_build_id	Parse build ID of ELF file mapped to vma
uprobe_write_opcode	NOTE:* Expect the breakpoint instruction to be the smallest size instruction for* the architecture
generic_file_buffered_read	generic_file_buffered_read - generic file read routine@iocb: the iocb to read@iter: data destination@written: already copied This is a generic file read routine, and uses the* mapping->a_ops->readpage() function for the actual low-level stuff.
filemap_fault	lemap_fault - read in file data for page fault handling@vmf: struct vm_fault containing details of the fault filemap_fault() is invoked via the vma operations vector for a* mapped memory region to read in file data during a page fault
do_read_cache_page
mincore_page	Later we can get more picky about what "in core" means precisely.* For now, simply check to see if the page is in the page cache,* and is up to date; i.e. that no page-in operation would be required
lookup_swap_cache	Lookup a swap entry in the swap cache. A found page will be returned* unlocked and with its refcount incremented - we rely on the kernel* lock getting page table operations atomic even if we drop the page* lock before returning.
__read_swap_cache_async
__try_to_reclaim_swap	rns 1 if swap entry is freed
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
hugetlbfs_pagecache_present	Return whether there is a pagecache page to back given address within VMA.* Caller follow_hugetlb_page() holds page_table_lock so we cannot lock_page.
mc_handle_file_pte
page_get_link	get the link contents into pagecache
