create_page_chain

Name:create_page_chain

Proto:static void create_page_chain(struct size_class *class, struct zspage *zspage, struct page *pages[])

Type:void

Parameter:

Type	Parameter	Name
struct size_class *	class
struct zspage *	zspage
struct page *	pages

1032

struct page * prev_page = NULL

1033

nr_pages = Number of PAGE_SIZE sized pages to combine to form a 'zspage'

1043

When i < nr_pages cycle

1044

page = pages[i]

1045

set_page_private(page, (unsignedlong)zspage)

1046

first free object = NULL

1047

If i == 0 Then

1048

first_page = page

1049

Private page markings that may be used by the filesystem that owns the page* for its own purposes.* - PG_private and PG_private_2 cause releasepage() and co to be invoked

1050

If Value for the false possibility is greater at compile time(objs_per_zspage == 1 && Number of PAGE_SIZE sized pages to combine to form a 'zspage' == 1) Then huge object: pages_per_zspage == 1 && maxobj_per_zspage == 1

1053

Else

1054

first free object = page

1056

prev_page = page

**Caller**
Name	Describe
alloc_zspage	Allocate a zspage for the given size class
