SeongJae Park 14fc42fa1b perf script python: Remove dups in documentation examples
Few shell command examples in perf-script-python.txt has few nitpicks
include:

- tools/perf/scripts/python directory listing command is unnecessarily
  repeated.
- few examples contain additional information in command prompt
  unnecessarily and inconsistently.

This commit fixes them to enhance readability of the document.

Tom Zanussi 1de7b7e89d perf script: Remove workqueue-stats script
The tracepoints used by the workqueue-stats script no longer exist so
trying to run the script results in:

  # perf script record workqueue-stats
  invalid or unsupported event: 'workqueue:workqueue_creation'
  Run 'perf list' for a list of valid events

So remove the script until it can be reworked using the new workqueue
tracepoints.

Jonathan Corbet 625f2a378e sched: Get rid of lock_depth
Neil Brown pointed out that lock_depth somehow escaped the BKL
removal work.  Let's get rid of it now.

Note that the perf scripting utilities still have a bunch of
code for dealing with common_lock_depth in tracepoints; I have
left that in place in case anybody wants to use that code with
older kernels.

Free the perf trace name space and rename the trace to 'script' which is a
better match for the scripting engine.
