Yang Jihong 55c41f2e4f perf help: Use HAVE_LIBTRACEEVENT to filter out unsupported commands
Commands such as kmem, kwork, lock, sched, trace and timechart depend on
libtraceevent, these commands need to be isolated using HAVE_LIBTRACEEVENT
macro when cmdlist generation.

The output of the generate-cmdlist.sh script is as follows:

  # ./util/generate-cmdlist.sh
  /* Automatically generated by ./util/generate-cmdlist.sh */
  struct cmdname_help
  {
      char name[16];
      char help[80];
  };

  static struct cmdname_help common_cmds[] = {
    {"annotate", "Read perf.data (created by perf record) and display annotated code"},
    {"archive", "Create archive with object files with build-ids found in perf.data file"},
    {"bench", "General framework for benchmark suites"},

  #endif /* HAVE_LIBELF_SUPPORT */
  #if defined(HAVE_LIBTRACEEVENT) && (defined(HAVE_LIBAUDIT_SUPPORT) || defined(HAVE_SYSCALL_TABLE_SUPPORT))
    {"trace", "strace inspired tool"},
  #endif /* HAVE_LIBTRACEEVENT && (HAVE_LIBAUDIT_SUPPORT || HAVE_SYSCALL_TABLE_SUPPORT) */

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.
