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.

2013-01-24perf script: Remove workqueue-stats scriptTom Zanussi1-2/+0
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.

2011-04-24sched: Get rid of lock_depthJonathan Corbet1-1/+0
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.
