Subject: [PATCH 71/74] perf script: Remove workqueue-stats script
From: Tom Zanussi <tom.zanussi@...ux.intel.com>
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.
