      perf config: Show the configuration when no arguments are provided · 41e0d040
      Arnaldo Carvalho de Melo authored 
      More convenient thah having to recall what letter is about
showing/listing/dumping the configuration, i.e. no arguments means
-l/--list:

  # perf config
  llvm.dump-obj=true
  trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  trace.show_zeros=yes
  trace.show_duration=no
  # perf config -l
  llvm.dump-obj=true
  trace.default_events=/home/acme/git/perf/tools/perf/examples/bpf/augmented_raw_syscalls.o
  trace.show_zeros=yes
  trace.show_duration=no
  # perf config -h

   Usage: perf config [<file-option>] [options] [section.name[=value] ...]

      -l, --list            show current config variables
          --system          use system config file
          --user            use user config file

      License cleanup: add SPDX GPL-2.0 license identifier to files with no license · b2441318
      Greg Kroah-Hartman authored 
      Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard...

      perf config: Reimplement show_config() using config_set__for_each · 4a35b349
      Taeung Song authored 
      
Recently config_set__for_each got added.  In order to let show_config()
be short and clear, rewrite this function using it.

      perf config: Introduce new init() and exit() · 8a0a9c7e
      Taeung Song authored 
      
Many sub-commands use perf_config() but everytime perf_config() is
called, perf_config() always read config files.  (i.e. user config
'~/.perfconfig' and system config '$(sysconfdir)/perfconfig')

But it is better to use the config set that already contains all config
key-value pairs to avoid this repetitive work reading the config files
in perf_config(). (the config set mean a static variable 'config_set')

In other words, if new perf_config__init() is called, only first time
'config_set' is initialized collecting all configs from the config
files.  And then we could use new perf_config() like old perf_config().
When a sub-command finished, free the config set by perf_config__exit()
at run_builtin().

If we do, 'config_set' can be reused wherever perf_config() is called
and a feature of old perf_config() is the same as new perf_config() work
without the repetitive work that read the config files.

In summary, in order to use features about configuration,
we can call the functions at perf.c and other source files as below.

    # initialize a config set
    perf_config__init()

    # configure actual variables from a config set
    perf_config()

    # eliminate allocated config set
    perf_config__exit()

    # destroy existing config set and initialize a new config set.
    perf_config__refresh()

[ 'init' counterpart is 'exit', not 'finish' ]
