Linus Torvalds e2125dac22 XArray updates for 4.20-rc4
We found some bugs in the DAX conversion to XArray (and one bug which
 predated the XArray conversion).  There were a couple of bugs in some of
 the higher-level functions, which aren't actually being called in today's
 kernel, but surfaced as a result of converting existing radix tree &
 IDR users over to the XArray.  Some of the other changes to how the
 higher-level APIs work were also motivated by converting various users;
 again, they're not in use in today's kernel, so changing them has a low
 probability of introducing a bug.
 
 Dan can still trigger a bug in the DAX code with hot-offline/online,
 and we're working on tracking that down.

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.
