mm/page_ext: add common function to get client data from page_ext
Patch series "add page_ext_data to get client data in page_ext".
Current clients get data from page_ext by adding offset which is auto
generated in page_ext core and exposes the data layout design inside
page_ext core. This series adds a page_ext_data() to hide this from
clients.
Benefits include:
1. Future clients can call page_ext_data directly instead of defining
a new function like get_page_owner to get the data.
2. There is no change to clients if the layout of page_ext data changes.
This patch (of 3):
Add common page_ext_data function to get client data. This could hide
offset which is auto generated in page_ext core and expose the desgin of
page_ext data layout.
