Linus Torvalds 0adc313c4f Changes in gfs2:
* Use iomap for non-journaled buffered I/O.  This largely eliminates buffer
   heads on filesystems where the block size matches the page size.  Many thanks
   to Christoph Hellwig for this patch!
 * Fixes for some more journaled data filesystem bugs, found by running xfstests
   with data journaling on for all files (chattr +j $MNT) (Bob Peterson).
 * gfs2_evict_inode refactoring (Bob Peterson).
 * Use the statfs data in the journal during recovery instead of reading it in
   from the local statfs inodes (Abhi Das).
 * Several other minor fixes by various people.

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.
