Linus Torvalds 5cdd4c0468 for-f2fs-4.13
In this round, we've added new features such as disk quota and statx, and
 modified internal bio management flow to merge more IOs depending on block
 types. We've also made internal threads freezeable for Android battery life.
 In addition to them, there are some patches to avoid lock contention as well
 as a couple of deadlock conditions.
 
 = Enhancement
 - support usrquota, grpquota, and statx
 - manage DATA/NODE typed bios separately to serialize more IOs
 - modify f2fs_lock_op/wio_mutex to avoid lock contention
 - prevent lock contention in migratepage
 
 = Bug fix
 - miss to load written inode flag
 - fix worst case victim selection in GC
 - freezeable GC and discard threads for Android battery life
 - sanitize f2fs metadata to deal with security hole
 - clean up sysfs-related code and docs

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
