Linus Torvalds 4c46bef2e9 We have:
- a set of patches that fixes various corner cases in mount and umount
   code (Xiubo Li).  This has to do with choosing an MDS, distinguishing
   between laggy and down MDSes and parsing the server path.
 
 - inode initialization fixes (Jeff Layton).  The one included here
   mostly concerns things like open_by_handle() and there is another
   one that will come through Al.
 
 - copy_file_range() now uses the new copy-from2 op (Luis Henriques).
   The existing copy-from op turned out to be infeasible for generic
   filesystem use; we disable the copy offload if OSDs don't support
   copy-from2.
 
 - a patch to link "rbd" and "block" devices together in sysfs (Hannes
   Reinecke)
 
 And a smattering of cleanups from Xiubo, Jeff and Chengguang.

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.
