Pull xfs fixes from Darrick Wong:
"I've got one more bug fix for xfs for 4.17-rc4, which caps the amount
of data we try to handle in one dedupe request so that userspace can't
livelock the kernel.
This series has been run through a full xfstests run during the week
and through a quick xfstests run against this morning's master, with
no ajor failures reported.
Summary:
- Cap the maximum length of a deduplication request at MAX_RW_COUNT/2
to avoid kernel livelock due to excessively large IO requests"

============
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.
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.
