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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
