Linus Torvalds 31990f0f53 The highlights are: 
- a series that fixes some old memory allocation issues in libceph
   (myself).  We no longer allocate memory in places where allocation
   failures cannot be handled and BUG when the allocation fails.
 
 - support for copy_file_range() syscall (Luis Henriques).  If size and
   alignment conditions are met, it leverages RADOS copy-from operation.
   Otherwise, a local copy is performed.
 
 - a patch that reduces memory requirement of ceph_sync_read() from the
   size of the entire read to the size of one object (Zheng Yan).
 
 - fallocate() syscall is now restricted to FALLOC_FL_PUNCH_HOLE (Luis
   Henriques)

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.
