Fengnan Chang e64347ae13 f2fs: support POSIX_FADV_DONTNEED drop compressed page cache 
Previously, compressed page cache drop when clean page cache, but
POSIX_FADV_DONTNEED can't clean compressed page cache because raw page
don't have private data, and won't call f2fs_invalidate_compress_pages.
This commit call f2fs_invalidate_compress_pages() directly in
f2fs_file_fadvise() for POSIX_FADV_DONTNEED case.

README 

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.
