Arnaldo Carvalho de Melo bc972ada4f perf trace beauty: Do not print NULL strarray entries
We may have string tables where not all slots have values, in those
cases its better to print the numeric value, for instance:

In the table below we would show "protocol: (null)" for

      socket_ipproto[3]

Where it would be better to show "protocol: 3".

      $ tools/perf/trace/beauty/socket_ipproto.sh
      static const char *socket_ipproto[] = {
            [0] = "IP",
            [103] = "PIM",
            [108] = "COMP",
            [12] = "PUP",
            [132] = "SCTP",
            [136] = "UDPLITE",
            [137] = "MPLS",
            [17] = "UDP",
            [1] = "ICMP",
            [22] = "IDP",
            [255] = "RAW",
            [29] = "TP",
            [2] = "IGMP",
            [33] = "DCCP",
            [41] = "IPV6",
            [46] = "RSVP",
            [47] = "GRE",
            [4] = "IPIP",
            [50] = "ESP",
            [51] = "AH",
            [6] = "TCP",
            [8] = "EGP",
            [92] = "MTP",
            [94] = "BEETPH",
            [98] = "ENCAP",
      };

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.
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.
