Jan Beulich 5c4e79e29a xenfs/xensyms: respect hypervisor's "next" indication
The interface specifies the symnum field as an input and output; the
hypervisor sets it to the next sequential symbol's index. xensyms_next()
incrementing the position explicitly (and xensyms_next_sym()
decrementing it to "rewind") is only correct as long as the sequence of
symbol indexes is non-sparse. Use the hypervisor-supplied value instead
to update the position in xensyms_next(), and use the saved incoming
index in xensyms_next_sym().

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 reStructuredText 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.
