This round introduces several interesting features such as on-disk NAT bitmaps,
IO alignment, and a discard thread. And it includes a couple of major bug fixes
as below.
== Enhancement ==
- introduce on-disk bitmaps to avoid scanning NAT blocks when getting free nids
- support IO alignment to prepare open-channel SSD integration in future
- introduce a discard thread to avoid long latency during checkpoint and fstrim
- use SSR for warm node and enable inline_xattr by default
- introduce in-memory bitmaps to check FS consistency for debugging
- improve write_begin by avoiding needless read IO
== Bug fix ==
- fix broken zone_reset behavior for SMR drive
- fix wrong victim selection policy during GC
- fix missing behavior when preparing discard commands
- fix bugs in atomic write support and fiemap
- workaround to handle multiple f2fs_add_link calls having same name
And it includes a bunch of clean-up patches as well.

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.
