Naveen N. Rao	d2ffb8d3cc	selftests/ftrace: Fix bashisms ... Fix a few bashisms in ftrace selftests.

Steven Rostedt (VMware)	8e5e19c1b9	selftests: ftrace: Add a way to reset triggers in the set_ftrace_filter file ... Just writing into the set_ftrace_filter file does not reset triggers, even though it can reset the function list. Triggers require writing the trigger name with a "!" prepended. It's worse that it requires the number if the trigger has a count associated to it. Add a reset_ftrace_filter function to the ftrace self tests to allow for the tests to have a generic way to clear them. It also resets any functions that are listed in that file as well.

Masami Hiramatsu	131f840d5b	selftests: ftrace: Initialize ftrace before each test ... Reset ftrace to initial state before running each test. This fixes some test cases to enable tracing before starting trace test. This can avoid false-positive failure when previous testcase fails while disabling tracing.

Steven Rostedt (Red Hat)	ee3988c77e	ftracetest: Add functions file that holds helper functions ... Created the file tools/testing/ftrace/test.d/functions that will hold helper functions. Current helper functions include: Add clear_trace() helper to reset the trace file Used as a descriptive name to show that "echo > trace" is clearing the trace file. Add disable/enable_tracing() helper calls Add calls that disable and enable tracing respectively by echoing 0 or 1 into tracing_on. Add helper reset_tracer() function Add a helper function reset_tracer() that will clear the current_tracer (echo nop > current_tracer).
