[PATCH V2 0/3] perf: add a dummy software event to keep tracking

[Adrian Hunter <adrian.hunter@intel.com>]

Hi

This is (version 2 of) an alternative to the 'keep tracking' flag patch
which is here:

	http://marc.info/?l=linux-kernel&m=137242545521246&w=2

perf tools is updated and a test added to demonstrate the
new event.

Changes in V2:

	perf: add a dummy software event to keep tracking
		Add Peter's Ack
	perf tools: add support for PERF_COUNT_SW_DUMMY
		Fix missing "dummy" in perf_evsel__sw_names
	perf tools: add 'keep tracking' test
		Let the test pass and print "not supported" if
		there is no "dummy" event
