Linux kernel source tree
162f6c69ea
Patch series "Cleanup free_pages() misuse", v3. free_pages() is supposed to be called when we only have a virtual address. __free_pages() is supposed to be called when we have a page. There are a number of callers that use page_address() to get a page's virtual address then call free_pages() on it when they should just call __free_pages() directly. Add kernel-docs for free_pages() to help callers better understand which function they should be calling, and replace the obvious cases of misuse. This patch (of 7): Add kernel-docs to free_pages(). This will help callers understand when to use it instead of __free_pages().

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.
