Arnaldo Carvalho de Melo 9a195da42f perf beauty: Update copy of linux/socket.h with the kernel sources
To pick the changes in:

  a6a6fe27ba ("net/smc: Dynamic control handshake limitation by socket options")

This automagically adds support for the SOL_MNC socket level:

   };

   DEFINE_STRARRAY(socket_level, "SOL_");
  $

This will allow 'perf trace' to translate 286 into "SMC" as is done with
the other socket levels:

  # perf trace -e setsockopt --max-events 4

This addresses this perf build warning:

  Warning: Kernel ABI header at 'tools/perf/trace/beauty/include/linux/socket.h' differs from latest version at 'include/linux/socket.h'
  diff -u tools/perf/trace/beauty/include/linux/socket.h include/linux/socket.h

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.
