Add set/end/wait_on_page_fscache() as aliases of set/end/wait_page_private_2(). These allow a page to marked with PG_fscache, the flag to be removed and waiters woken and waiting for the flag to be cleared. A ref on the page is also taken and dropped. [Linus suggested putting the fscache-themed functions into the caching-specific headers rather than pagemap.h[1]] Changes: v5: - Mirror the changes to the core routines[2].

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.
