page_ext is the only user of 'status_change_nid', which is set in online/offline operations, to know to which node we are adding/removing memory. Prior to call any notifiers, the memmap is initialized via, which among other things, sets the node the pages belong to, to all corresponging pages. This means that there is no need to keep using 'status_change_nid' since we can derive the node from the pfn. This will allow us to finally drop 'status_change_nid' from the memory_notify struct.

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 reStructuredText 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.
