Objects that are potential for swapping out are (1) willneed (ie. if they are purgable/MADV_WONTNEED we can just free the pages without them having to land in swap), (2) not on an active list, (3) not dma-buf imported or exported, and (4) not vmap'd. This repurposes the purged list for objects that do not have backing pages (either because they have not been pinned for the first time yet, or in a later patch because they have been unpinned/evicted.

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.
